Looking for our next RV....Considering an A - Advice needed

Love the long trailer it and Robin Williams RV are must watch for all.
given the amount of usage you have described I would consider renting. You could try several layouts and you have none of the following depreciation, upkeep, storage, wash and wax, oil changes, your present policy should cover your insurance needs or you can get rider cheap for week.
We are full time in 4 slide dp and lovein it. But it is not cheap.
I would not let my dog ride in either of 2 5s I have owned.
