Your post sounds like you may not have had any type RV previously. Aside from the size/weight issue here is some thoughts. My neighbor just retired and bought his first RV. A large TT bunk house model. He did not know enough about RV's to make a wise purchase. There are so may issues to understand. One thing he did regret is that he did not get a combo propane/electric water heater. Just propane. The water heater is located next to the master bed. When he is in a full service campsite with all his grand kids the propane only water heater goes on and off all night waking him up. He has to turn it off all night to get his sleep. There are many options issues to understand, so do your homework first.
