Most comfortable riding

The one that's paid off.

The easy answer is probably the truck with a GVWR much higher than the weight of the camper.

Of course this a subjective topic. However not quite as much as good looking.i have a 2001 dually and need more comfort

Thats like asking which truck is the nicest looking with a truck camper.

Lot's of variables here but my 2017 Ford F350 is very comfortable going up and down the road with my camper.

That's a hard one to determine since there are so many variables. I've carried the same TC, the one in my signature, on both a '06 Ford F350 SuperCab and my current '10 F450 which is a crewcab. They both were diesel, long bed, 4x4 with 19.5 tires, air bags, and Energy Suspension bump stops. The F450 rides more comfortably probably because it is longer and wider. It also improved when I switched to Bilsteins. The F350 had Rancho 9000s.
