[MENTION=57488]faitro11[/MENTION], the bottom line is a 3/4 ton truck is not what you need for a Solitude.
Here is my experience.....
I have about 3400 lbs on my pin.the pin of my 310GK-R. One measurement (actual weight scale readings) was about 3300 lbs.
I have a Reese Goosebox, and F-350 Long Bed.
Last year I upgraded from an F-350 Short Bed with a 330 lb DEMCO hitch and a MorRyde pin box to the Gooseneck. I upgraded to a LB to lose the 330lb hitch, gain 500 lbs of payload capacity (difference between the F-350 SB and the new L

and pick up another 244 lbs by using the Reese Goosebox.. Here are my calculations for various hitch combinations.....
Here are some calculations I made when deciding to make the change.....
MorRyde Pin Box: 138 lbs
Demco Slider: 331 lbs
469 total
Reese Goose Box: 225 lbs (-244 lbs)
Gen-Y: 134 lbs (- 335 lbs)
B&W Comp. 20K: 153 lbs (- 378 lbs)
Demco 8550033: 177 lbs (- 254 lbs)
With a short bed you would likely need a slider hitch for a Solitude if you expect to make a sharp turn; folks will say you don't; I had the RV hit my cab without the slide trying to back in my driveway (pretty much a 90 degree turn). So when you hear about folks that say they do it, they do, but for me I didn't need the risk.
One more thing.... I'm not sure this is still the case but I bought mine (5 years ago) from LazyDays I had to sign a form saying I would tow it away in with a 1 ton truck; I spoke with others who had the same experience.
I hope some of this helps. I know it might not be the feedback you want.
