It does OK. I have to keep it in 3rd for most of the trip. Especially on any hills. With stock tires and stock gears it'd do fine but I'm rockin stock gears and 31's for now. 4.10's in the future. It does a pretty good job of stopping it.
Older pop ups tend to weigh more than newer ones. I'm going to guess this one is along the lines of 1500-1700 pounds loaded. Stump pulls his with his red XJ and it's way bigger than mine but it's newer and probably weighs around the same. Maybe he'll chime in on how much his weighs.
I'm hoping to trade for a smaller one later this week.
(Probably already posted this but oh well)
I'll sell the one I have now. You should buy it.
