We had a 2005 Jeep Grand Cherokee with a Hemi and lift. It seemed to be a good combo. Made at least at least 30 climbs over the continental divide with no major issues. I feel it probably one of the best proving grounds for TV/TT combos. There is a reason why several companies test their vehicles out here. While it felt like a strain on the engine (probably my nervous tendancy) the Jeep maintained 55+ anytime I asked for it.
The dealer recommended simple hitch with a anti-sway bar. It seemed OK, but I always wondered if I needed a WDH. If you have load leveling, it may be moot.
I needed a brake controller too. Unknowing, they put in a new harness and charged me an arm and leg for a Tekonsha Primus IQ. An adapter can be had that will prevent from having to do the harness from Amazon along with a cost effective controller. The Tekonsha performed great! I recommend getting ahead of the camper.
