While I don't have such a new MH I am going through some of the same things as you with my '75 GMC Eleganza II. I bought it because it only has 1 step to get in it. Steps are my problem. I paid $10K for it and have added another 10K and looking at another 3-4K getting it ready. Right now it is sitting in Orlando, FL at GMC Coop Motor works. I don't know if I could get that much out of it but it does only have 56,000 miles on it. I am hoping to get a couple years of use before I have to give up RVing. I have found it is not as enjoyable travelling alone.
Adding up I did spend 35+ nights in my Roadtrek this year.
