Rock Tamers for Alaska

I've heard some people say that Rock Tamers type mud flaps are a must for driving to AK. We have a 5th wheel and will be driving north on the ALCAN and south on the Cassier Highway next summer. I'd rather not get them if they aren't necessary, but also don't want damage to my rig. Anyone have experience using them or not using them and not having issues?

I had to look up what they were.

We had a motorhome and had the heavy mudflaps behind the tires. We didn't get any damage for rocks flying on our towed Jeep.

We have seen folks actually removing their full heavy mudflap midway up the Alaskan Hwy. on the the rear of the motorhome as they traveled to Alaska and talked to them and saw the damage to their towed car and windshield. There was actually a layer of heavy rock laying at the base of their windshield of the towed vehicle.

I also zeroed in on opposing traffic going through Salt Lake City one rainy day. The stiff mudflap across the rear of motorhomes was throwing an arch of water on top of the hood and into the windshields of their towed vehicles. That convinced me that I didn't want one of those flaps.

Now..... you're talking about on the rear of your truck but just behind each tire; not all the way across. Hopefully, someone will reply on that set up. I just thought I'd let you know how having a stiff flap on the rear of a motorhome doesn't protect the car.

If you have a good flap behind your tires already, I would say you don't need the additional, expensive Rock Tamers.

Have a great trip!!

Here is what I did to protect our toad.
Mudflap extenders and a hula skirt for the rear.
Four trips to Florida and no trash on the toad, and no chipped paint.

I believe if I was towing a 5r or bumper pull types and planning on running any length of gravel road I would actually try and devise some way to attach a length of rubber belting across the front of the trailer 24 to 30s in width or height if that makes sense. We ran the Alaskan hwy in 1976, 1200 miles of gravel and 7 flat tires! I realize its different now!

I run Rock Tamers and they do a good job of keeping rocks and mud off the trailer. Note that if you have a diesel with all the emissions equipment intact you may need to put a heat shield on to protect the rubber from melting when in regen mode. My Duramax spits out pretty hot gases when in regen...
