My ORV Mfg Creekside 23BHS is upgraded with a bunch of MoreRyde components.
4" added travel with suspension upgrade at
http://www.morryde.com/products/sre4...system-triple/ (actually this is better than ORV's “Titanium” upgrade which only has the CRE3000 3” travel suspension.)
Also did the extra side to side strengthening with the MOREryde X-factor brace that goes clear across the underside
www.morryde.com/products/x-factor-crossmember/
and the Heavy Duty Shackle kit
www.morryde.com/products/heavy-duty-shackle-kit.
Also upgraded to tough E load-rated tires instead of C rating.
I bought it originally for forest service roads capability without beating up the structure, but only did that once, mostly all trips to the beach. However it turned out that tarmac roads gave it just as much exercise to smooth things out. e.g. Going over the super rough pavement near the top of Hwy 8 in the Oregon coast range was a revelation and other whoop-de-doo rough roads like the northern approach to Pacific City.
I highly recommend the upgrade. Over the Hwy 8 slide-patched tarmac, in the pickup truck we got quite tossed around but the trailer floated gracefully over those turbulent sections.
(btw I'm selling the trailer - it's in classifieds item 20407.)
