Have you looked at any with all your 'wants'? :) Doing so may change your mind on some things. $$$$
It sounds like you enjoy public parks - national, state, etc. and some boondocking. If you do those in the eastern states, think 36' max.
We full-timed 16 years traveling mainly in the West in a 33' 5th wheel and 40' motorhome. Our motorhome fit in the same parks as the 33', including national parks, national forests, COE, state parks, county and city parks. We loved boondocking on a river or lake by ourselves. We had no problem with the 40' - in the West.
We did just fine without a residential refrigerator, washer and dryer or dishwasher. If we ordered new now we still wouldn't order them because of the type of places we like to go. If you just do RV parks with full hookups then go for them. We also ordered our motorhome purposely with only two slides because of having to maneuver among the trees in public parks. Now they probably don't even build a larger DP with only two slides. Used you could find one.
Good luck finding what's best for YOU. P.S. We loved our Newmar!
