Newbie. Wanting to buy a class A

All MHs in the years you are looking at will be built on the same chassis, use the same appliances and accessories . The discriminators would be the storage, full basement storage or the small cut out door storage that you see in Class C's, FW ,grey and black tank storage if you plan on dry camping. Another discriminator is the box construction, but this is harder to get info on as to the materials and process used to bond the side walls together. I like the hung wall concept rather than bonded panels only because they are not laminated so they can't delaminate. Newmar, and Monaco use this method. I would look for units with end caps. I would also look for units with two full pass throughs so you can store bikes, ladders, tables etc inside the MH. Some shorter MH's have only one AC this may be a discriminator depending how and where you camp. I would focus on the features that you want on the MH based on how you plan to use it and the general condition rather than brand, they all have problems. Check for water leakage and maintainance records.
