OP... you can full time in ANYTHING. We fulltime in a Keystone Challenger purchased used 4 years ago for a price so low we could fire sale it today and still make money. First rule in RV shopping is never buy new. They ALL have quality control issues and you will most likely need to get items fixed during the first year of service. DO get an idea of floorplans you like and weights your tow vehicle can handle. Take the time to look for the deals. For example we came across a last year of manufacture Teton Homes that was showroom new with the hdt to tow it asking 55k. We were not in the market for that type of floorplan but someone would get a great deal.
Re Palomino Columbus: it is a newer brand and they are only just now starting to get a decent sized owner base. Imho they are too new to know how well they last. We love the look and layout of their big bunkhouse but are not convinced yet that they will last.
