I hadn’t heard of the Camco Trekker either. But did a search and learned Camco produces the Eaz - Lift line. I deliver Airstreams Forrest River and Gulfstreams from the Mfgs to dealerships the past 4 years. Many dealerships sell Equalizer, Blue Ox, Husky and then Eaz - Lift as their cheaper entry level WDH.
I sometimes see Eaz - Lift Recurves and will have to look for Trekkers. Modern WDHs with built in sway control seems to have obsoleted older style WDH’s with seperate add on friction sway control like Adventure posted. I didn’t even know they still sold those new. I mean like outside Harbor Freight or something. But Camco still lists it on their site.
Reviews on Eaz - Lift haven’t been the best in the past but I have never used one. You might look for reviews on the Trekker. And repost your question as Eaz - Lift Trekker as many like myself might not recognize Camco.
