I live in ontario canada. the local dealer has these "sport" models in stock. From what I can see they are stripped down surveyors (i.e. no torsion suspension, no enclosed underbelly - this is what I noticed looking at the outside of the trailer) that are at a lower price point??? I hope so at least, seeing how I already own a 235 rks I did not check into the pricing. The one I was looking at was the surveyor 291 layout called a 280BH, minus the stuff I mentioned. I hope that you weren't lead down the wrong path when you bought your trailer. The suspension, enclosed underbelly etc. are what makes the surveyor line ( not "sport") a better product. I looked on their website and it does NOT state these differences... (that I could find) Like I said, the 280bh I saw was the same layout as the 291 only without the suspension and enclosed underbelly.
maybe the one I saw was totally stripped down?
