Question:

I have Rock Tamers on my 2020 Toyota Tundra. Bought them thinking they would protect my boat and trailer on gravel roads. First trip and I have chips all over the trailer. Is there some way to adjust them? I was looking at adding the screen in between the flaps.

Hello Randall,

Thanks for writing in.

I am sorry to hear you ended up with chips on your trailer after that first trip. You will want to make sure your Rock Tamers # ERT00108 are adjusted with the boat and trailer hooked up to your Tundra. Rock Tamers recommends having the bottom of the flaps about 3" to 4" off the ground. You can rotate the support arms to adjust the height and also adjust the width to get the best coverage behind your tires.

I see you have since added the Rock Screen # RT37FR, and that is exactly what I would recommend for the gravel roads you are traveling. It fills the open area between the two Rock Tamers flaps to help catch rocks and debris that can otherwise make it through the center. You also picked up the Fender Guard Mud Flaps # 337B1237PPB, which will give you even more protection from debris being thrown toward your boat and trailer.

It sounds like you are getting your setup ready for some serious backroad boat adventures! Where are you headed with the boat?

Thanks Kate for confirming my choices. We have a dozen or so small lakes around here. Most are only accessible by gravel road. A lot of the busy lakes here get pressured making it difficult to find and catch walleye.

@RandallG You said Walleye and had my full attention. Their teeth and faces always freak me out a little, but they are great eating! I like to fry mine up to make little sliders on Hawaiian rolls with some spicy slaw.... mmmmmm! I will be at the Lake of the Ozarks this weekend, so hopefully I get some in my belly! Luckily we do not have to deal with gravel roads getting to the boat ramps we go to, I definitely see why you want to keep things protected. - Tight lines =)

Randall, I had the same issue initially. I called into Rock Tamers for help. He had me rotate the flaps so they tip outward towards the trailer. It doesn't seem like it makes sense but it made all the difference. Now no more rocks getting thrown at the trailer.
