I'm glad you defined "affordable" ("around $70-$75k") because what is affordable for one person can be insanely expensive for someone else.
Yes, look for a good used RV from a top manufacturer. Late last year we picked up a very well cared for 2008 Tiffin Phaeton for a small fraction of the new price. Both the interior and exterior look practically new. The original owner not only took the depreciation hit but dealt with the teething pains of first-owner problems getting sorted; I got a partial list of them when I called Freightliner for history on my coach.
There is a Facebook group for used Tiffin coaches and, I'm sure, groups exist for other makes as well - both Class A and C.
We have always bought used and by doing careful homework have never had any regrets in 35 years of RVing.
