Does anyone have experience with a airplane type castered nosewheel installed in the triangle area of trailer tongue. Seen one at the racetrack on a good sized enclosed race car trailer, tow vehicle was class C motorhome. Owner couldn't say enough nice things about how it improved every aspect of combination rig handling. Suspention system for nosewheel was pretty beefy coil spring and maybe interior shock absorber and system was adjustable for how much load to carry. Didn't get into number crunching with the guy, but I'm wondering, if your tow vehicle is pickup dually (cummins of course) with max length slide in camper and bumper hitch is extended way out and you're nearing GVWR, 12,000 lbs but have plenty GCWR, 9000-11000 lbs, will the nose wheel work well to share the 10-15% load trailers need at the tongue thus keeping some load off the long extension bumper hitch and GVW. Thanks for any links and advice. Jim.
