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.
