The DP does have it benefits. Ease of set up, comfort driving down the road, lots of storage. But it's now 9 yrs old and always in meed of some repairs. I am very handy and do almost all the repairs myself. But of the 4 vehicles I own, none can be flat towed. So then I need another vehicle. Once we set up camp, I spend very little time inside, rain or shine. My DW is happy inside in her spot on the couch to read. We really don't need all the room a DP has. With the kids no longer going we can get away with much less gear with us so storage is not that important. A tow vehicle can be written off by my business.
I'll work on her slowly. This may take some time.
