We carry our bicycles on the back of our 36′ fifth wheel trailer with a Kuat NV bike rack inserted into the trailer’s hitch receiver (we reviewed the Kuat bike rack here). We installed this bike rack in 2012 and it has been great for the past five years of our full-time RV travels.
To keep the bike rack from dragging on the ground in crazy places like steep gas station ramps or deep gulleys on small roads, we had a “Z” shaped “hi-low” hitch riser made. This raises the rack up quite high, so now the first thing to hit the ground is the hitch receiver itself rather than the bike rack.
As is often the case with hitch receivers, the bike rack isn’t a perfectly tight fit in the hitch receiver riser, and the bottom of the riser isn’t a perfect fit in the trailer’s hitch receiver either. So, the whole bike rack tends to wiggle.
We’ve used various shims to make it all tight, but too often they would wiggle loose over time, and eventually the bikes would be jiggling all over the place on the rack again.
Last fall we stopped in at JM Custom Welding in Blanding, Utah, to talk with Jack, the man who had made our “Z” hitch riser (more info about it here). We wondered if he had any tricks up his sleeve for making our bike rack arrangement less wobbly.
It turns out that he had solved this very problem for other customers by making a hitch tightener. This is essentially a hitch clamp that fits over the end of the hitch receiver and snugs up whatever is inserted into the receiver with some lock washers and nuts.
So, we got two of them, one for the top and one for the bottom of our “Z” shaped hi-low hitch riser extension.
The difference in the amount of movement of the bikes was absolutely astonishing. They were rock solid now!
After installing the hitch tighteners, which was just a matter of tightening the nuts, Mark drove the rig around the JM Custom Welding dirt lot while I walked behind and watched the bikes, and they were steady as could be.
But unlike the shim solution we’d used before, these hitch tighteners have stayed tight without needing any adjusting or fuss for several months and several thousand miles of driving on all kinds of roads.
The hitch tighteners do make for some extra steps if we want to move the bike rack from the hitch receiver on the trailer to the hitch receiver on our truck. However, we’ve started hauling our bikes in our truck in a different way using a furniture blanket, so there’s no need to take the bike rack off the trailer any more.
Jack makes these hitch tighteners in batches, so if you are passing through Blanding, Utah, perhaps on your way to or from the beautiful Natural Bridges National Monument, just a mile or so south of Blanding you can stop by JM Custom Welding and pick one up! In 2016 the were $38 apiece.
We discovered later that hitch tighteners of various kinds are also commercially available. So, if Blanding, Utah, isn’t in your sights, you can choose from many different kinds of hitch clamps online.
However, a visit to Jack’s welding shop is very worthwhile, especially if you need any kind of custom metal fabrication done on your RV. He is very creative and does excellent work.
While we were in Jack’s office, we noticed a display of his for a folding storage solution for the beds of pickup trucks he’s created that fits right behind the truck cab. He calls it the “Jack Pack” and it is essentially a framed canvas storage bag the width of the truck bed that is easily opened to throw your bags of groceries into and then easily folded away when you need to haul lumber or fill the truck bed with something else.
If we didn’t have that part of our truck filled up with extra water jugs, we would have snagged one of those from him at the same time!
