We have a basic 8-1/2 ft x 16 ft body cargo trailer - we tow it behind our 3500 - using a Super-Truss system and an Air-Safe suspension coupler.
We don't like travelling without it because it completely eliminates the fore and aft "camper jiggle" we get when not trailering. Our camper does not have cowl struts like a Lance.
The ride is eerily smooth on the busted highways of our region when hooked up to the trailer via the Air-Safe system.
The trailer is our garage - bikes, plus chairs, outdoor cooking stuff, tools etc.
We like.
