    Hello Everyone,

    I'm considering upgrading to an enclosed car trailer. The open trailer has been good, just decided its time to upgrade to the security/convenience of an enclosed unit.

    My question is how hard is it to mount an electric winch on the floor of an enclosed trailer? I don't have an enclosed trailer yet, so don't have a floor or frame to go check out. I know that ordering a new trailer it is an option to have a winch mount installed, but what if I buy a used trailer, then I would need to mount a winch myself.

    Just run bolts through flooring, hit framing, maybe some backing plate? Mount a battery box in the trailer, connect to the winch? Do I need some kind of circuit breaker?

    Thanks, I'm a noob at winch mounting!

    You can have a winch plate welded to the frame rails under the spot you will use. It won't need to be anything massive, usually 1/8" or less thickness, study the plates used under your tie down points for an example. Then just drill through the floor and the plate and mount (usually just 2 bolts). A long remote cord is a big help. A wireless remote is wonderful.

    A battery box (inside or out) with power run to the winch is what I use. A breaker/fusible link is not a bad idea, but remember the winch could pull some large amps. I also have the battery tied into the 12v circuit powering the trailer lights and coming from the tow vehicle, so it gets some charging while towing.

    Thanks, that's good info. Very helpful. Wiring into the 12V system of the trailer is an interesting idea. Only gets 12V from the trailer leads so charging must be pretty minimal. As long as the trailer battery doesn't get too drained from using trailer light while parked, this seems like a a good idea.

    I've always wanted a winch in my enclosed trailer but never installed one because it would add to the tongue weight. And the tongue wt on my trailer is about as high as it should go. Before you put all that weight up front, check your tongue wt.

    Jim, not sure about your concern of weight on the tongue due to a winch? A winch would only be used if my car didn't run. It would still be strapped down in same location in the enclosed trailer. An electric winch would be mounted on the floor toward the front of the trailer, with a battery nearby (I assume), the the winch/battery combo probably weighs about 50-60 lbs max ?

    A wench may weigh a bit more though :)

    Link below is to a few models of the Superwinch. Weight of the winch of these 3 varies from 38 lbs to 42 lbs. This along with the battery - probably adding 100 lbs to the front of the load.

    I do not have a winch in my enclosed trailer.... but may decide to add on this year.

    I got a Warn winch (I prefer those to Superwinch, but YMMV) along with a receiver hitch carrier for it. You can then get cable kits that you can put on multiple vehicles to connect it to. Since I off-road some, I've got those on my Jeeps. I haven't gotten around to it yet, but my plan for the trailer is to put a mount plate in as described above, but weld nuts on it and then use massive "thumbscrews" to attach a receiver hitch to the floor, which I then obviously put the winch in. Then use the cable set Warn sells to plug it into the battery. That way I can take it with me, but I don't have to have it in the way unless I need it. Probably adds 20-25 more pounds to the whole deal, if that's a concern for you.

    (On the Jeeps, I only wire the rear since they have mounted winches on the front already. Occasionally there's no way to pull yourself out in that direction, though.)

    Ok, I get it now. People who are already pushing a tongue weight limit (probably 500 or 750 lbs) are reluctant to place another an additional 100 lbs inside the front portion of the trailer. I really think that the additional weight would be somewhat distributed through the trailer framework so its really not an addtional 100 lbs on the hitch ball. Besides, don't most folks throw occasional equipment into the enclosed trailer (wheels, floor jacks, shopping trips at Wal-mart in Topeka) that are not planned?

    I like the idea of mounting a receiver hitch in the trailer, and having the winch mounted on a 2' hitch, neat idea for portability. Will have to think some more on this.

    A side thought, are there portable winches that could hook up to the front D-rings of a trailer, then a power source, and pull a car into a trailer? I really don't expect to winch a car into the trailer often, but nice to have the capability when stuff goes bad. This way the winch is kept packed away till needed.

    Thanks all. Appreciate the info and feedback. Learning more each day!

    If you want cheap, just fab a plate that you mount your winch two that has a couple hooks and use straps to hold it to the D-rings. If you want something you can use in other situations, go to Northern Tool or Tractor Supply and buy the 2" receiver hitch that's made to bolt to a bumper. I'll bet you could either hook to that or just bolt rings to that you could hook to, then get a winch with receiver hitch. That's what I was planning to buy to bolt to the floor in my trailer (with the huge thumbscrews).

    The only thing I'd worry about with the strap idea is odd twisting and such. Either way I'd recommend buying the optional fairlead (I think that's what it is called). It's the roller piece that you bolt to the front of the winch. That will help protect your cable should it twist in odd ways or the cable gets at an angle that it would scrape the opening in the front of the winch.

    As has been stated, I'd definitely recommend either a wireless remote or a long wired remote so you can load and drive at the same time by yourself.

    Couple other ideas, if you don't want to constantly trip over your winch, you can do a couple of things. I built one into a floor using a welded steel box that mounted on the underside. A flip up cover kept is concealed when not in use. Some mount them all the way to the front using some of the front wall structure for strength. I've also seen peolpe mount them off to the side, and use a pully to route the cable through. Pully is fastened to the floor using a d ring or E track.

    BTW, adjust tongue weight with car position, no?

    Here is the 3000lb superwinch unit I use. http://www.superwinch.com/pages/gp/gp3000.html

    It weights only 15lbs. I run it with a 25lb Honda sized battery. It seems small, but pulls the 2500lb car in with ease (even when I left the car tansmission in park, it pulled the trailer to the car!) If battery weight is an issue with respect to tongue weight, consider direct power from the tow vehicle. Either way, as pat mentioned, moving the car a bit will control the tongue weight.

    To clarify ... my trailer is small and my car just barely fits (both width and length). There's no room to move the car forward or backward to adjust tongue wt. The page listed above wasn't accessible when I tried to view it. But such a fine winch must be extremely expensive. The winches I can afford weigh alot more. Another 75 pounds at the front and I'd be very uncomfortable with the wt. I suppose I could mount the winch at the rear and use a pully as mentioned above. That would actually take wt off the tongue.

    Maybe when I have a spare day to do the job right I'll take on that task. But for now, I'll just continue to push the car into the trailer.

    Thanks again guys. Must be nice to be able to push a car onto a trailer. No wonder you aren't too concerned about having a winch. I'm probably going with some kinda portable winch, with a deep cycle battery (like a yellow top optima). I'll check out some of the lighter weight deep cycle batteries if i can find any, but I really prefer the deep cycle type for the ability to recharge many times. I actually killed a red top optima from letting the battery run down too often. Yellow top has been fine (car sits a bunch).

    Etrailer.com lists that winch for $350 (try adding a www to the link above...I know it's there, but this site seems to strip it on the link-through). On a budget, try the smaller [url=http://www.etrailer.com/mm5/merchant.mvc?Screen=PROD&Store_Code=E&Product_Code=1220200&Category_Code=TRWNCH]2000lb winch[/url] ($150).

    Try browsing around the Superwinch site
    http://www.superwinch.com/pages/choose/tips.html

    Or, you could just go with the Chinese-made alternative from [url=http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=91781]Harbor Freight[/url] (or Tractor Supply, etc) for around $100. Not something for everyday use, but for occasional use, it might work. The disadvantage is less efficient motors (meaning more current draw from the cheap winch), and shorter life of usage.

    Jim, your winching what....a 900 lb car? A cheap, crappy winch would be more than enough for your formula car. (Still in the FF, aren't you?)

    Regarding the trailer tongue weight, have you looked for axle position adjustments? Many trailers can be adjusted a bit. Does your car sit facing forward or backward? (I'm sure you already thought of that, but just throing it out there.) Anyway, I would rather have too much tongue weight than not enough.

    Yup, still have the FF. It goes in backwards. Even with the anti-sway on the trailer hitch, the trailer will still sway if the car goes in frontwards. It's odd ... if I go in frontwards, there's not enough weight on the tongue. If I go in backwards, the tongue wt is real close to being too much. This trailer demands alot of tongue wt in order to have stability.

    This is probably due to axle position but there's no allowance to adjust the axle positions. It wasn't a name trailer. And I'm not going to invest more money/time into the trailer because eventually I'd like to get a new one.

    The problem with cheap crappy winches is that they usually have a very slooowww line speed. I'd end up pushing it in anyway except for those post-event loadings on a 100 degree day when you're beat.

    Yeah, I'm particular. Bit it's really not a terrible thing pushing a 900 lb car into the trailer, unless the trailer is parked facing the wrong way on an uphill slope.

    For fixing trailer sway, what kind of tires? Real trailer tires (as opposed to passenger car tires) will go a long way to helping with sway, especially if they are on the correct rim. And if you can extend your trailer's tongue, that can help too (take a look at a Uhaul trailer...I don't think there are any single-axle trailers that are more resistant to sway, and the secret is skinny trailer tires and REALLY long tongues).

    I use real trailer tires.

    The tongue is about 3 or 4' long. How does that compare to other trailers?

    Summit has the Superwinch gp3000 winch on their web site for $279.95.

    Not sure how much shipping would be though...

    3' is bad, 4' is better.

    As an example, a friend's single axle trailer has a 6x12 bed with a 3' tongue, with the axle in the middle of the bed (which tilts). Axle track width is 7'. It is hurt by having 225/70HR15 passenger car tires on 5" rims (built-in sway), but with that short tongue and wide track, it needs about 25% or greater tongue weight to keep it from swaying above 60mph. Trailer tires might help somewhat, but another 2 feet of tongue would make a huge difference.

    The Kansas Region Solo trailer is similar; the axles are in the center of the trailer, rather than towards the back. It has other problems (like most if its weight in the back), but if it were possible, moving the axles back 2-3' would make the trailer much more stable (it has several hundred pounds of weights on the tongue to give it enough tongue weight).

    Imagine a triangle with the axle as the base and the tongue as the point, The smaller the angle on the tongue, the more stable (in a straight line) the trailer will be.
