Ian,
I have been RV'ing since 1981, having owned several travel trailers towed behind cars and trucks, one 5th wheel, and four (4) different motorhomes. They all have advantages and disadvantages. There are many determining factors on what kind of RV to get, and whether a tow vehicle is needed. If you tow a travel trailer or 5th wheel, you obviously don't need to tow a vehicle. With a motorhome, it's VERY convenient to have a 'toad' behind you, to drive in local areas when your motorhome is parked at the campsite.

Towing a car that can travel 4 down, vs having to have the drive wheels on a tow dolly, is more convenient. Otherwise, at the campground, you have to find a place to put the tow dolly in addition to you tow vehicle at your campsite. We selected the Ford Escape Hybrid because it can be towed 4 wheels down, due to the eCVT hybrid unique transmission. Prior to that, I towed a 1999 Saturn, that was designed to be towed 4 down. Almost all manual transmission vehicles can be towed this way. Only a select few automatic transmissions can be towed 4 down, without external transmission lubricators or a driveshaft disconnect for rear wheel drive cars.

OK, I've gone on long enough. Suggest starting by going to the GoodSam Club website, or Google around for RV specific sites. There's tons of information out there.

My wife and I belong to two camping clubs, and can't wait until spring to get going again. Our 1st trip out will be to the national RV rally in Perry, GA in March

Good luck,
