Living space is key. Last year I was on the road for 121 days. Drove from WI to Santa Monica and then to Orlando and back to WI. We took our time doing about 400 miles a day. Of the 121 days we spent 17 on the road. The rest were parked where RV never moved. So I say make sure you love the layout. I have had four gasser sand presently a 2016 Winnebago Suncruiser 38Q. Love the layout and on this one the ride is very good. DP's are great and I could not find a layout I liked so much in this length. I have traded a lot. Generally made good deals but I left a lot of money in those motorhomes none the less. Every trade was about layout. I ride is tolerable and other things have no red flags then layout and living comfort should turn your day. If the DP layout pleases you then an older DP is better v a newer gas. Most of us can't see inside all the moving parts. Somethings will need replacing and others maintenance on a used motorhome. That is a given no matter what you purchase. But if there are drawbacks to the living space that jump out at you walk away. They will get worse not better the more time you spend in it.
