I have an 04 Fleetwood Discovery diesel pusher and tow a 28' cargomate trailer that is loaded with tools, spares and a golf cart. Lots of hills out here n the west and I have no complaints. More power would be nice but it does well. My advice is buy the most power and number of slides you can, we have four. The power is obvious the more slides make staying in it less cramped. Here is our rig. next up is a stacker.
