7000lb is doable, the Trailhawk trim XJs were rated for 7200, automatics in other trims 5000lb. But yeah, I wouldn't do it. I towed 4500 through the rockies in my 98 manual and it was... fine, but didn't love the downhill curves.

I don't think I will be able to get a camper in the size that I want / need at that low of a weight unfortunately

Then you're probably pushing the design limits of the XJ for towing what you want. This isn't an EV problem in this case unfortunately. You have to take into account the other limitations of the vehicle for towing beyond powertrain.

Braking, frame strength for the hitch, relative weight of the towing vehicle vs the trailer (The XJ is nice and light), strength of all the drive-line components under load. Keeping any fluids in the driveline cool, which is a little easier in the EV. Presumably you'll have trailer brakes as well. Sure I'm missing a couple things...

Here's a nice thread on XJ (non EV) towing: XJ towing capacity

I've read the manual rated only to 2k lbs because you'll chew up the clutch. I towed way more than that with it but yeah, the clutch got toasty at times. Either way, the range math makes this tough. I think packing batteries into the XJ you're only going to get just a bit north of 100mi range, before you stick 7000lb behind it.
