I probably wouldn't put it on the quality coach list but that is just my opinion. Now for your questions:
1. Generator - is a diesel generator even available? If you can get one with it, that would be my choice.
2. Look on the driver's door and get the OCCC number for this coach. If it is less than 1000 lbs, you won't be able to carry enough to take much of a trip.
3. Your Wrangler weighs a bunch. Get it weighed and you will probably find out it too heavy for a Sprinter chassis. Your max tow weight is about 4200 lbs.
We downsized from a Phaeton and it is a chore. You have limited weight carrying capacity and storage space but you can do it if you want to.
