Let me use the example of my current coach which fits into your size range, though is a bit older, it is a 2002 Safari Trek 2830, which I bought at the age of 14 years in 2016 for about $22,000 total from a private party seller a thousand miles away in Florida, add in another $1,400 retrieval cost (airfare, fuel, RV campgrounds on the drive home), plus another $500+ spent at Walmart on equipping it for the journey (sheets, towels, pillows, blanket basic pots pans, soap, toilet paper, flash light, basic tool kit, food, ...), add in about $850 for a year of insurance and I am at close to 10% of post tax purchase cost spent before I even made it home.
Since buying the coach I have averaged somewhere over $5,000 per year in maintenance, upgrades, etc. until covid hit which I would split about equally between being immediately necessary (ie failed alternator, seized brake caliper), optional maintenance and routine wear items (tires, shock absorbers, etc.), optional upgrades (LED lighting, Magneshade sun screen, smart tv,etc.), this might be slightly tapering off, but may just be luck as I fully expect to need to replace the now 20 year old roof air conditioner and water heater before much longer.
Adding all this stuff in, including fuel, camp sites, insurance, etc. over the last 5 years once will see buying it was just about the cheapest thing I have done with this coach. We are leaving on a 2+ week, 2,000+ mile trip in about 12 hours in the coach, where I fully expect to spend around another thousand dollars or more with the majority of it being on fuel.
Now with the Covid craze I have seen coaches identical to mine selling in the $30,000 range such as this one
which is identical to mine, minus various upgrades mine had done by the previous owner like new seating, 400 watts of solar panels, pure sine inverter, new refrigerator etc., but even at that price I would not make my money back.
