As another poster suggested, post your question on the Suites owners website. Your question is a little vague, be specific about your concerns. We own our 2nd Drv unit. Problems? On our Select one of the AC's went out, Drv didn't manufacture that. On our Mobile Suite an AC went out in the first year, Drv didn't manufacture that. Our Dometic frig on the Select was great, in our Mobile the Dometic 1350 has had 2 cooling units go out, then Dometic replaced the entire frig and that one lasted less than 60 days. We are taking it in again at the end of the month for another cooling unit. If that goes out we are putting in a residential frig, but Drv didn't manufacture that either. I would buy another, quality frames (yes, Lippert built, but each manufacturer has their own specifications), 3 1/4" walls, good insulation all around, good factory support. www.suitesowners.com. You need a big truck, we had a 2007 Select Suites , it weighed 16,200(don't make that model anymore, replaced with the Tradition) and now have a 2012 Mobile Suite, it weighs 19,400. There are many owners that have purchased a 2nd & 3rd Drv unit, that says something. Rolling Retreats in OK, Wheels RV in AR and RV's for Less in TN seem to be the favorite dealers.
