I just purchased a host aspen sb. It was one of the east coast deals where I did the best research I could do, but it was purchased having never seen one in person. Just curious if anyone else on this...
But having a single slideout TC on our 2500 is pushing it, IMHO. I would guess that you are going to be in the 4500# range once loaded with water and all your gear.
We were over on rear tire loading. I now have 8000# capacity on F & R axles.
I agree that you should be seriously looking at 19.5" tires/wheels.
