We've owned two travel trailers, four fifth wheels and now our DP MH. The last fiver we had was a Cameo before they sold off to Thor, 40' , top of the line full body paint. It would Rivel any MH. Had a diesel dually to pull it.
Climbing up and around the bed hooking up and unhooking got really tiresome ( bad back). There had been some hitch issues with multiple hitches, braking ( hated controller). It was our second vehicle and I drove a company car for work. My wife after time wouldn't drive it anymore. So there was anothe car purchased for her. The nice truck just sat until camping, insurance , maintenance, etc.
So one day we looked at our current MH and never went back. Love it way more than any of the the other 6 platforms. Many reason discussed already, ease of hookup, no need for a dedicated towing truck. Way more comfortable driving, view better going down road, easy setup. One thing that really has me scratching my head is those who claim a fiver has more room, storage etc. In our current setup we have every bit of storage we had in our last 40' fiver. There's also as much room inside with our layout.
If your into rear kitchens, I guess that excludes DP MH's. But being you kept your truck, maybe you were never on board with the MH?
