Just be aware and look into the in's and out's of using a dolly and the weight of that car you have. You want to tow the lightest car you can NOT what your MH is rated to tow.
Some CG's will not let you put your dolly along side your MH at the campsite. Some will make you park it somewhere else on the grounds. And do a search on those that used a dolly and the problems they encountered with the loading and tie down of it.
IMHO and what I did when I was not sure if I even wanted to tow. I bought a used small car that could be towed four down. Investment was small I figured I could sell it and get my money back if it turned out not to be what I wanted to do. You can't do that if you feel the need to buy new.
Find the "lightest weight" car you can find.
I found a real nice 'used' Chevy 4x4 Tracker for a real good price. It was so light weight I didn't even know it was back there and ended up using it for 6 years full timing AND sold it for more than I paid for it when I pulled off the road!!!
