Looking to get into RVing.. need help

Thanks... I guess it's more than finding a place to place our head and fill our stomachs. Was also looking at the ability to use "my" bathroom when needed (Which for my wife is about every hour and half)... opposed to many of the raunchy roadside stops, though we did find that Love's truck stops had some of the cleanest restrooms around. not lugging a few overnight bags into the hotels at night or making sure the cooler is still full of ice. I would imagine that they would depreciate quickly, as it is more of a vehicle than a house and we know that one is usually good investment whereas the other tends to be a vacuum. My has mentioned that I wouldn't be able to cruise along at 80+ mph like I do in the truck, nor will I see anything around the 25+ mpg I was getting either. Hoping an RV would offset the hotel costs and the need to not "push" to get to the next city to find a room. I'm going to continue to do my homework and thank you all for helping see some options. I'm still not 100% convinced it's not for me, but have seen a few more options now.
