rock and splash guard for RV's

X2 on the grill protection for the radiator. Did mine specifically to stop bugs from clogging the radiator fins on our first trip north. Well it works so well that it is still there. Stops lower 48 bugs as well. I used simple nylon screen wire zip-tied onto the grill.

It has been 6 years. I really should replace it.

In my opinion, the most fullproof effective way to protect a toad from ALL the elements while towing is to simply place it inside an enclosed cargo trailer.

The more effective protection for open trailer equipment I seen for auto transporting is shielding the entire front of the trailer with aluminum diamond plate in a "V" shape pattern (similar to a front of a boat) while leaning back at a 45 to 60 degree angle so that any rocks and debris will deflect well away from the trailer.

Rock and splash guards along with mud flaps commented by others are right on the money with the pros and cons, for best results you more likely will have to customize whatever you are using to some degree to improve it better and or to make it last longer without extensive adjustments or repair.

In Alaska, it is state law that all commercial AND passenger trucks are solely equipped with rear mud flap-rock shields-guards, I took note seeing this one configuration someone was using as on my trucks I bolted two 1/4 inch thick semi truck mud flaps together (to make it a much more durable 1/2 inch thick) and placed them hanging underneath the rear of the truckbed, cut a portion of the mudflaps to make a hollow rectangle slot towards the bottom side of the mudflap for more airflow going thru the mudflap (so that the mudflaps do not want to whip upward but rather lightly sway with the airflow while staying in a verticle position), as I also installed mesh screen in between the two mudflaps bolted together that cover the open space rectangle slot, as the remaining mudflap material that was cut out I utilized it and installed clear across the bottom of the mudflap giving it it's thickest and strongest point of one inch thickness (so the mudflap doesn't twist side to side).

With the extra customized work I done to make them more durable, it has paid off so far as they lasted 14 years and counting.

I also highly recommend installing some wire mesh either inside or outside the front of the grille in order to protect the radiator core from flying debris which can potentially become damaged, as Joe mentioned one important element of oncoming vehicles driving too fast in loose gravel stretches coming at you, to where when permitted I will pull over and slow down or stop at an angle while giving the inconsiderate in a hurry people the evil look while they disregard other driver's rigs upon spraying loose gravel all over your rig(s) when crossing paths on the road.

We don't have a rock guard and in Whitehorse we saw folks removing them because of the guard throwing rocks at their toad. We saw a layer of rocks laying at the windshield base. We just have flaps behind each tire and we didn't get any damage on the whole trip. Just remember to drive slow!

I disagree. I believe the solid rock guards are very good IF, AND ONLY IF, they are installed as directed. Many people feel lower is better and then cause more problems than they solve. Be sure you have the clearances the particular brand of rock guard specifies. Also use chain to support them and use a piece of 1 1/2x1 1/2x1/8" steel angle at the top to stiffen it. The thin steel strap they sell for them bends too easily. If you want to see how a rock guard protects, drive along side an RV on a road and observe. The hairy kind streams just about straight out and might as well not even be there. If you're still concerned about glass and toad dings, consider Coast Line RV and Offroad.We've used their coach bra's and toad covers for years and love them. We go to Alaska every other year (06,07,09,11,13)and have close to 200,000 pulling miles. Putting a Coast Line Cover on and off takes about 5 minutes and if you keep it clean does NOT damage paint under it.

In past trips I have taped cardboard or bubble wrap onto the front of the 5er basement & bubblewrap over the truck headlights. No night driving so lights are not used. 2 trips. 1 tiny ding on trailer front cap & 1 tiny widshield chip.

The full width ones that are solid are not good. Many are so close to the ground that when the Moho suspension goes up and down over bumps, they will drag the ground and add to the road debris being thrown back at the toad. The brush types seem to work better. Flaps mounted , just behind the individual rear duals also seem to work well. Many that use the curtains that are horizontal and fill the space between the Moho and the toad probably gets the best reviews from those using that type.
Some like the verticle shields mounted just in front of the toad, many I have seen are made of a clear poly plastic. Be careful of putting a bra on the toad as dust will get under it and act like sandpaper to the toad's paint.

A few have reported good success taping bubble wrap over the windshield to protect the glass, the same with headlight covers. The covers on some toads are plastic to start with so probably nothing needed. I have busted a couple of headlights over the years, but this was back before the Alaska Hwy was paved.

If I was towing my Jeep, which I don't take a toad with our truck camper, I would probably look into getting one of the horizontal curtains and keek as much debris as possible going under my toad. Of course, it isn't just junk kicked up by your vehicle that can cause damage, but traffic you are meeting that is going way to fast for road conditions. About all you can do then is to stay as far right as you can and slow down or even stop if you have time and can safely do so.
