FWIW, old rig was a NL 811 sitting on a ’01 Dodge quad cab 2500 standard (short) bed SRW 4x4 CTD. Quite a few mods and still never felt real comfortable though we did ok over the 5 years we used it. New rig is a ‘15 Adventurer 86 SBS sitting on a ‘11 Ram Mega dually 3500 4x4 CTD. Added air bags, that’s it. Our new to us camper is configured for a short bed so it has the Inan gen.
COG is pretty much the same (about 1” diff) between the two rigs. Very comfortable ride, extremely happy with the stability on the road and when parked. TC’s are very similar in weight, just much more comfortable all the way around in the “new” rig. Some folks think the Mega Dually looks funny, we like the looks and interior space, personal preference.
