Have dwindled the search down to two RVs any advise?

I would go with the Fleetwood. We have had a Bounder and an Expedition, and were pleased with both of them. We looked at Georgetowns and did not think that the fit and finish was as good. Southwind is at the top of the Fleetwood gas models so it should be better. What are your options on engines and transmission? Chevy workhorse engine with Allison transmission is better option, primarily because of the Allison. Also consider floorplan and what the DW likes.
