^^^smartest thing^^^.

Carry a couple of chunks of 2x4 to stack under jack, in case your trailer frame rails are higher than the extended height of the bottle jack.

Cheap auto parts store / Harbor Freight / etc. bottle jacks are perfect. I keep one in the big trailer and one in the nose-box of the old open trailer. $20 will get you a 4-6 ton jack. If you have a jack, you won't need it. If you forget it, you'll immediately need it.

Once forgot to return bottle jack to enclosed trailer, and had a blow-out on I81 in PA. Managed to scavenge enough junk & scrap to improvise a "ramp thingy" (like in pix above), but it was a pain whacking thru the undergrowth to find all that crap. Props to PA for never cleaning up their highways.
