I'll answer part of your questions. Newells are designed and built from the ground up to be a certain type of coach. Prevosts are a bus shell that is converted by different converters. Each company has their own way of working around the Prevost bus designs. So each Prevost could have different items, etc. depending on which company did the conversion and what the customer wanted. Newells are custom built but the basic design is somewhat standard. Newell has 24/7/365 customer support on the entire coach. Both are excellent choices.
