You might want to see if you can rent a motorhome similar to the one you want to buy and take it on an extended vacation to see if it is going to be big enough for the two of you. I agree with the statement, "buy your last motorhome first". We started with a 40ft with one slide and recently went to a 42ft with 4 slides. We couldn't be happier. The extra room and amenities make it worth the extra cost. Don't make an expensive mistake by purchasing a MH that won't end up matching your future needs. Good luck to you and I wish you the best.
