Here are my new Rock Tamers mudflaps (by Enkay). I'm very happy

with how they function and their quality. Due to the weight and cumbersome size of the Rock Tamers and Equalizer hitch assembly, I prefer to leave the assembly on the truck at campgrounds (as shown in the first picture below on left). However, with the trailer unhitched, I noticed the Rock Tamers "rock" a little up and down at each end due to hitch slop or rattle. The weight of the trailer tongue prevents this when hitched up. So, exploring the subject of hitch slop I found a solution I'm happy with that I use in conjunction with the Rock Tamers. The solution is the Hitch-Vise, the picture below on the right, which is a bracket-type vise that grips together the receiver and the drawbar. The Hitch-Vise is exactly 1 inch wide, which is all the space that was available between the Rock Tamers bracket and the front edge of the receiver. The whole assembly is solid now, hitched or unhitched. Cost for the Hitch-Vise is $30 plus shipping. I made a 1,400 mile trip this summer and it all worked great. The link for the Hitch-Vise is:

I bought the Rock Tamers at Cabelas, which occasionally has a free shipping sale. The current price at Cabelas is $189 for the plain black mud flaps. The Cabelas link is:
