id say hi-lift. the other one is overkill. sometimes buying the name means buying quality (warn, Marlin(yota guys)), and sometimes buying the name is just that- buying a name. you can buy (or make) a bigger "foot" for the hi-lifts. having that connector clamp on top is nice to hook to things to make the jack into a come-along but with a few bolts, a welder, some extra steel, and a good imagination you can make one. im looking into making a slide on type adapter that is a chunk of pipe (cut in half) with an ID the same as my bumpers and sliders pipe OD, so i can have a more "secure" lifting on those peices. if you have a winch youll have a stronger, faster, and farther reaching version of the come-along.
the spreading part ive never had to do so i cant help there.

"Also, keep in mind for a taller rig like yours (or i suspect it is) you will probably want the taller, 60" jack. I know the shorter jack wouldnt do much of anything for my rig, and I bet you sit close to the same height."
this time a quadrilionbajillion..... i have a 48 incher and i have 36ish inches till the sliders and more till the bumper. im out of jack before i have fully released the suspension- on flat ground. so i carry a few chunks of 4x6 wood (and alot of hope that i break down on the flat) till i get off my lazy butt and buy the 60 inch version. i also carry a chunk of chain to wrap around the frame and axle to help with having less droop.
