Thank you-- it was helpful

HI- I just saw this message. I don't have a 20' any more, but they are probably all about the same. Right now my 25' is parked on an unloved site, so I can't give you a good measurement. But a couple of things: Only jack from the designated jacking post (marked by a 2" square piece of aluminum on the belly pan. It also probably has a big "Jack Point" arrow pointing to it. It will be a foot or two behind the axle.

It takes a fair amount of travel for the jack to raise the wheel. So that's what you need to have in the jack. The bigger the jack, the greater the travel. But you probably don't have to go with the biggest jack you can fit under there as you're carrying boards or something to level the trailer when you park so you can use them to raise the jack AND to put on top of the jack to spread the force over the jack point.

Hope this is helpful. If it isn't, someone else will be able to help I'm sure.

Happy Camping!

Looking at purchasing a bottle jack for 20 ft bambi--- would you happen to know what is the maximum height of the jack that will fit under trailer before extension. I would measure it myself, but out of state and was going to order one online. Any suggested make?
