Thanks for your replies, Mike & Carol, and Sea Dawg! Sorry for the response delay, we were packing for our 7 month RV trip to Nova Scotia from Michigan. Day 6 now, Boston! I will have a base + no pets. It might be mostly parked. Tow vehicle: I'll have to get a bigger one. We have a dually for the 43' 5th wheel + Toyota Sierra for my A-Liner Scout for now. I like the Oliver floorplan: rear bathroom makes it much more spacious. Olivers seem to be the best. Why get something else only to move up later? Better to start right at the top!
