I worked on motorhomes and trailers in the collision industry for ten years and there is one thing I can say is, they all leak in one form or another. You need to be ready for a lot of maintenance work on these things. The roof and windows should be checked once a year min. for areas that water can enter. Most are kept outside year round and the UV eats them up. You also have a few batteries to keep up. I have seen some really bad things when you don't Winterize the rig as well. I would recommend if you are only going to use it a few times a year RENT ONE and save yourself a lot of grief. Knowing how the house portion of these rigs were built I would never own one.
