I think we will see similar inflation across the options. That's not really what drove me to purchase either of the HF trailers though.
I had a welded Carry-On 5x10 which was generally fine, but it had the ramp and welded side panels, and weighed a crap-load, making it challenging to move around when totally empty. I sold it for the light maneuverability of the heavy duty HF 4x8, sacrificing no weight capacity (since I had kept the 5x10 unregistered and restricted from a full ton in Oregon). The difference in moving it around by hand is massive, requiring no jack to move it or change a tire.
My hope is that the new HF 5x10 is a good compromise between the two on those points. I didn't really need more weight capacity so much as want the extra space for utility use. It's at least 250 lbs lighter than my old 5x10, and without the rails, a lot more adaptable, but the old 4x8 is what I plan to build on over the next few months only because I want to keep the frontal area to a minimum for aerodynamic benefit. Fully built, I should still be able to easily move it around some by hand. I doubt that would be the case with the 5x10 and a similar build.
