I don't know the weight of the things you need to haul around but you will find that a gasser has a lot less carrying capacity than the DPs. Last year I sold my '03 Mountain Aire that was in excellent condition for les than the $34,000. It had 43K miles on it. One of the huge reasons for a Newmar is that there can be no delamination on them because they do not have laminated walls. It was also time for new tires at $3000. That is someth9ng to consider on used MHs. My gas Newmar had a limited carrying capacity that was no problem for us but could be with a child and full load of instruments.
