I just bought a 5th Wheel trailer that had a good quality hitch that is incorporated into the frame. Advise that I got from friends that tandem tow boats and quads is do not tandem tow a quad with a lite 5th wheel as they have had and have seen too many bent frames. Just my 2 bits.
My buddy and I both have the Gator Glides (From Devon) on our trailers as they are a little easier on the knees if you kneel down on them while clamping the sleds down. However the Super Glides are better on the ramps as they have better grip. So far they are holding up quite well, we use out...
Cabella's, Campers Village both have the Flare's and Launching Pen's. Lori at Zacstracks also sells them https://snowsafety.infusionsoft.com/app/storeFront/showProductDetail?productId=235 Bear Bangers also work on the same launcher / pen
I bought a Sled there last year. Clutch missing critical components, ended up costing me a S@#$ load to completely rebuild the clutch. Never again will I set foot in there!
I bought my set at Echo on 118th ave. They ordered them in for me. Love them, the only thing that I am going to add to them is a good ear bud, so you can hear them better while riding.
