Shocks on a trailer??? Only the most expensive, luxury models have that equipment. I don't know of any "entry level" (cheap) or "mid level" (nicely equipped) trailers with shock absorbers installed as OEM. Even some "top line" (expensive) trailers don't have them....

As for "trading up to a motorhome"... I've got a friend with a 1.5 million dollar motorhome. It's in the shop right now (at the factory) for repairs after his recent trip on I-70 through Colorado. And, for "equal opportunity" it's no better through Arizona, Texas, Mississippi, Louisiana, Alabama, Georgia, Tennessee, Ohio, Michigan or Wisconsin* on any of the interstate highways, so buying a motorhome won't improve your comfort level, not to mention how much lighter it'll make your back pocket.....

* You can fill in the name of nearly any other state if you want to be included in that list.... Ain't none any better when it comes to "the good old days" when roads were quality constructed and properly maintained....
