If you're towing a car behind that RV, I don't see much difference between that or towing a fifthwheel or travel trailer. In both cases you need to hitch up and unhitch. (Full disclosure, we fulltime in a fifthwheel.)
As far as helpful suggestions for the OP, I think one of the best things you can do (besides checking out the websites already recommended) is go spend some time at RV dealers or better yet at an RV show or two. Sit in the rigs that appeal to you. Picture yourself hanging out, doing hobbies, cooking, watching TV - whatever you like to do. Look for a good fit for you and your likes. Think about where the items you need to have along will be stowed. If you have pets, where will the food and water bowls go? Where will the cat litter box go? (W/D enclosure works great if having a W/D in the rig isn't a priority.) If you watch TV will you get a crick in your neck if you sit in the chair you like best? Those sorts of things make a lot of difference down the road.
When we had a better idea of what we wanted in a rig we took a mock PDI (pre-delivery inspection) list with us to the RV shows and spent some time looking in cabinets and crawling under the rig and opening the basement power access and so forth. That really helped us narrow down our choices and get a good idea of fit and finish.
Hope this helps!
