I like Rexhall, was also on my short list. I do not like, though never had, propane generators. Also, I'd rather have a generator with medium to higher hours, then one with low hours - they need to be run frequently, to keep things working.
You mentioned two RV's. You may have already done this, but I will make my normal suggestions:
-Go visit RV shows, large dealers, and walk thru as many kinds of RV's as you can.
-Learn the differences. Slides, driver slide only, leveling vs auto leveling, CCC and related weights, tank capacity - such as Grey, gas vs diesel, side vs rear radiator, 4spd vs 6spd, compression brakes vs exhaust brakes vs retarders, raise rail, paint vs gel coat, dual pane windows, insulation value, water heater vs aqua/hydro hot, etc., etc.
-Sit down and make your list of 'Must Have's' and 'Like to Have's', so you can do some comparison when looking.
-Set your budget range.
-Reserve budget capacity for baseline maintenance catch up
-Come up with a short list of manufacturers and models that seem to fit your lists, then go shopping.
Also, IMO, drop age to reach budget level while still retaining the highest quality coach that you can. Quality lasts. The 'bones' are what count, as all components of all coaches will need the same maintenance and eventual replacements. With manufacturer's, you can usually fine the model line where you start getting the higher quality 'bones' but without all of the 'glitz' that add weight and costs. If the 'glitz' is your thing, great
Many, many good used rigs, and it is a buyer market.
Have fun, and best of luck,
