Information overload

Four hours is not even a beginning to learn about RVs. You will be very crowded in a class B. There is not much storage space there. RVs in mist cases do not do good in cold weather so you would have to plan to be some place a little warmer in cold weather. Not all RVs are created equal. Some have insulated walls and some don't. The larger ones have more storage but I remember one review I read on a MH with great storage and low carrying capacity. The magazine said it would be great if you wanted to carry ping pong balls. I suggest you hit some dealers and look at various floor plans and other features to learn what you like and don't like. Is the bathroom usable for everyone? Is there adequate kitchen space to prepare food? Is there room to hang clothes for the 3 of you? If this is your home for 1-2 years it has to be livable for that long. I would suggest towing a car for the economy. You plan to spend a week in various locations. Driving a car around that gets 20 mpg is a lot better than driving a MH around getting 6-8 mpg in town. It also gets old to have to pack up everything to go someplace with the MH rather than hop in a car and leave the camper set up.
