@ryan : Can (do you want to) flat tow the jeep?
The primary issue I found with slide in camper was weight.
Last year, I was looking at a F250 diesel 4x4 SuperCab. The brochure said maximum GVWR was 9,400 lbs/2,740lbs payload. But the truck in question was a King Ranch (not an XL) which dropped the payload to 2,340lbs. Unfortunately, I have to take: Me, the sandwich maker, the dog, a couple tool boxes out of that, I also need to install the camper tiedowns. So, ready for the camper, I only had 1,800lbs payload available.
Now, the brochure for the slide in camper (Adventurer 80GS) said it said 1,466lbs dry weight. So, I thought I would be about 300lbs to the good. But the brochure doesn't include the battery in the camper, the propane cylinder, the stairs to get in, the pots/pans/dishes, the BEvERageS & food for the long weekend, the sheets/pillow/blankets (the upgraded mattress - if I wanted to feel like I slept on the ground, I would have used a tent) or the Fresh/Grey/Black water. In all, it added up to well over 600lbs.
The result was >300lbs over weight - which kyboshed any plans to get a hole in the water to pour money in (aka a boat). I was too far over to even be able to move battery/propane/spare tire/camper jacks to the trailer to make it work...
My secondary issue was loading the camper.
Getting lined up square and centered enough was almost a divorce issue. Her visual perception isn't good enough to help line up, and she won't back the truck under with me directing.
So, we got a 5th wheel.
And she loves that I can back the truck under the pin by myself and be locking the hitch faster than she can round up the dog.
And even my daughter was impressed by how well I could back the 5th wheel into a spot. (way easier than a hitch trailer).
Lastly, the 5th wheel has a pin weight of around 900lbs (actual weight), so I've 400+ lbs payload available on my F-150! and scary amount of GCWR available.
While tandem towing i.e. boat behind 5th wheel is legal in Alberta/Saskatchewan/Manitoba, it isn't in British Colombia - and the nicest/closest lakes are in B.C.
Therefore, I have been trying to promote that the ideal solution is a truck camper on gooseneck boat trailer. In your case, a truck camper on toy hauler gooseneck trailer.
You won't have a weight problem - either GVWR or GCWR
The slide-in camper was too big to fit through garage door, so storage is more/less the same (stays at an RV lot).
The camper & toy can be removed; then you have a trailer for hauling lots of things.
Couple additional things we learned about campers:
Hard sides are nice during in-climate weather (we use it over Xmas at ln-laws; we were fine in -40C).
North/south bed is really nice if you/significant other don't have identical sleep schedules - crawling over each other tends to disturb sleep.
The extra height in the bed balcony area was comforting to significant other (she felt claustrophobic in the east/west bed of the slide in).
Larger fridges in bigger campers are really nice (separate freezer vs freezer within fridge)
Shower wasn't as much of a requirement as we thought; the campgrounds we stayed at have had showers. They also allow disposing of the grey/black water which eliminates excessive weight.
The trailer is lower so tows on the highway very stable. It would be a issue on say a forest road, but the slide-in was an issue with branches too. And it often reminded you it was top heavy.
