Class C - with ability to tow

Best to rent something and then tell us more about your preferences and needs.

For starters, your Grand Cherokee is likely somewhere around 4500 lbs. (check your stickers/manual)

Most "C"s are on Ford chassis with pre 2020 being a 6.8 V-10, and the newer having the 7.3 V-8.
2016 and older will have the 5 speed tranny, newer has the 6 speed.
General reviews are that the 6 speed is a major upgrade.
Most will have a 5000 lb tow cap, with a few offering 7500.
Either drivetrain is capable of what you are looking at.

As to the C itself, floor plan is your first major concern, determine what types of spaces you need. Separate rear bedroom etc, If you plan on dry camping (Boondocking) tank sizes become important, anything over a 35 gallon black will last a couple weeks generally with anything under 50 gallons on the grey likely limiting you to a week or even less. Fresh will match your grey production but its pretty easy to carry extra fresh in a couple of 5 gallon totes/jugs.
As to how where to travel, I'd suggest starting on Youtube, and then from the working on the road side check out www.Escapees.com they have a lot of discussions on their site covering much of that as well as membership gaining you some discounts on campsites.
As to wifi, if good speed is needed for work, explore cellular data plans and their abilities, campground wifi is hit or miss, mostly miss. They will advertise it, but for anything beyond checking e mail and basic web surfing it often is inadequate.
Hopefully this gives you some ideas of where to start.

Any E450 motorhome will pull you jeep.

There is a huge variation in Cargo Carrying Capacity so it might not hurt to start figuring what you might need to pack for long trips, and this might limit the max size unit that will work for you, since larger = less CCC.

I agree with the comment recommending renting a couple of Cs before you buy to decide on a floor plan and with being very careful about CCC and the C maximum tow weight. Do it once carefully.

Check your real Jeep weight for towing . If you plan to haul gear in it bc you plan long term stays , be sure to take cargo into consideration.
**if you plan to 'flat-tow' the GC, make sure you can. Not all are flat towable, depends on the drive system.

I agree 100% with PartyOfFive, RENT first !

See how much room, floorspace, you need with the 2 dogs always in the way.
* Beware that many 'C's use a base entry level chassis without power seats or power mirrors. I personally like the Jayco seats with leatherette and power swivel bases.

Check the comfort level of seats in the cab as well as in the rv. I would want recliners or at least a sofa as well as a dinette .

If you are used to towing a TT, expect a MH to be more noisy when driving it. You don't hear things rattling around when towing a TT.

Why limit yourself to a Class C?

X-2, Class A will likely have a lot more room.

Class C would be marginal for towing your car. Super C or Class A.

Forget the bank account !

Please define "marginal". The E450 can tow a 5000 lb Jeep with a significant margin in GCWR. GVWR is not a factor when flat towing since there is virtually no tongue weight.

OP, this will turn into a giant discussion. But your options are few and basically any E450 with a V10 or 7.3 will pull a toad no problem. Bout the same as a pickup with the same motor and a big TT would pull.
I’m not even a ford guy but I’d rather have either of those than a 6.0 Chevy if I was towing.
And those are your 3 basic options in standard class c mohos.
