I think with a used 15 year old MH how it was maintained is more important than the brand. Last year I looked at 3 very nice 7 year old MH's in the ads but when I inspected them in person the owners never were up on the roof to caulk and water leaked inside on one and rotted the inside wall the other two had exterior delamination among other issues. Newmar is nice because it can't delaminate but it can leak and have other problems like any other brand. They all use the same appliances, drive trains and other accessories. There are personal discriminators like large FW tanks and storage bays if you dry camp or maybe HWH jacks are better than some of the other brands but most of the other stuff is pretty subjective.
