Yeah, but by the time you 'unstore' everything, connect it all up, _get the generator to start_, do the tire change, and 're-store' everything, you could've just used the hand tools. After futzing with the truck jack to change a trailer tire on the road, I've started carrying our aluminum floor jack to get an axle off the ground to do the change. A toolbag always goes in the truck when the trailer is hitched, and it always has the breaker bar and all required sockets.
But I digress. This is a thread about getting insurance for a trailer so you don't _have_ to carry all the junk.
