My wife wants to get an RV but I don't know much about them. Thinking of a TT in the 24' class. It's the 2 of us and a 5 year old so we want room for a friend of his to be able to tag along, too. Wife wants a toilet at least. Mostly looking for long weekend trips along the mid-atlantic. Maybe once or twice a year we'll do a whole week. I'm leaning toward something with a tandem axle for redundancy. When I'm looking at different ones online it lists the 'dry/unloaded weight'. How much is a good amount to add to get a real weight when looking to make sure I can tow it safely. I have 3 different dealers in town so I'll be looking at them, none of which are Camping World. What sort of things should I be asking or looking for?
