Trailer stone guard

Hi All. Have just purchased a camper trailer and was wondering about the effectiveness or otherwise of stone guard/flaps on the back of the cruiser. I have seen some full width and near to the back of the vehicle. Any thoughts re design, shape fitment construction and materials would be appreciated. I have some ideas in mind but not sure if I am on the right track.
Thanks
Regards Alan

Mate go here Campertrailers forum or My ush home and get some ideas from there seeing as your not getting any from here.

Mate the stone guard on the camper is affective but you need to have good mudflaps on the car as well, i know i have broken 2 rear windows even with a stone guard on our camper.

I have just completed fixing our stone guard on the camper to be more affective also i'm making a flap to go all the way across the back of the car as well.

You can never have enough protection.

Alan,

There is a school of thought that says a full width mudflap, or even mudflaps just behind the wheel, create a low pressure behind themselves,especially if they are close to the road. This in turn lifts rocks and gravel which the closely following trailer hits and throws forward at the car.

Even if this is not true, no mud flap will stop every rock flying up from the wheels. Most camper trailers have some form of stone guard fitted onto the trailer. Mine is a heavy piece of shade cloth strung loosely on a frame and angled down across the front of the trailer.

The idea is that rocks tha fly up will hit the lose material and be deflected to the ground. This protects both the car and the camper from stone damage. I have still managed to break a rear window, although I believe the rock was thrown up by a truck going in the opposite direction, and my trailer now looks like it has been sand blasted on the front corners. I am thinking of making my stone guard a little wider and a little higher.

My car is fitted with the standard Nissan mud flaps.

Hope this helps
Duncs

Sounds like a combination of both or at least the better guard of the two options should be on the trailer.

I forgot to add that we are putting a rear window protector on the rear window as well, it's basicly a piece of perpex cut to the same shape as your rear window and is velcroed on to the window.

Look in here OBIE'S rear window saver

Its pretty easy to make your own rear window protection, I did a couple for my GQ. There is a Polycarbonate sheet called Tuffak, it is quote "virtualy unbreakable" but really easy to work with and cut with a jigsaw, or to drill, it doesn't crack like Perspex. I used 3 mm for the GQ's 2 rear windows, but there is a thinner more flexible thickness for larger windows. Just make a paper template first.

Gajam(?) - where did you get the stuff you made your rear window protector of? Is it readily available? Is it solar protected - I know the one from Obies is -

I got mine from a perspex place in Seaford Vic, I went in looking for ordinary Perspex, and they put me onto this, I only have a scrap left, and can not read what it says.But apparently it is designed for this sort of thing. It is about double the price of perspex...cost me $70 to do both windows. from what I can read about its properties and strength id be suprised if it wasn't UV resistant, but can't tell you for sure

Thanks for that Gajm (got it right that time!) - I am in Frankston so will investigate - got to be cheaper than $865 that we paid for the rear window - Nissan Terrano II - could only get genuine Nissan - no aftermarket made - and it happened in Qld - guess where the glass had to come from - yep right - Melbourne, oh, well, c'est la vie.

Hi Julie

We used empty beer box cartons...though any type of cardboard boxes would do, we just taped them on to the back of the car, they do a great job, and is an option for you if the polycarbonate one is too expensive.

If you'd like a pic of what I'm talking about, click the rig pic and send me an email

cheers

Ouch! we went to the Corner last year and there was a landcruiser with the same CT as us (stone guard on wrong), and actualy from our suberb.. with his back window bleep tered. It made us realise we were just lucky, and that if it did happen we'd be in the same boat as you were, which is why I whacked on the plastic.
On a recent trip my daughter dropped a log onto my rear side window and when I had it replaced the window guy gave me the prices of the rear windows, which were hideously expensive, i'd hate to pay for them to be shipped interstate.

I had a look at that site with the rear protection, it's pretty well what I did. I used non stick velcro all around the window tho, and used the clear liquid nails to stick it on. I don't want it flying off at 100 k's on the freeway. I notice he has rubber stops to keep it off the window, I had used a couple of sticky velcro squares in the centre to do the same thing.

I also drilled a tiny hole in each corner of the plastic on about a 45 degree angle facing down to let condensation out, with the rain we have been having they were getting a couple of foggy spots in the corners, so that lets them vent.

The Perspex place is in Stephenson rd in Seaford. Pioneer plastics at #6, phone 9775 0203 I think!! there are a couple there, and I usualy just drive up. if you are heading to Dandenong its on the right side, Its not the plastics place on the corner, but the one next door set further back, it has a big sign saying Perspex cut to size.

It is Tuffpack atoglass if thats any help.

Have a look at the way Adventure Camper Trailers do there stone guards.
It keeps all the stones & most of the dust under the trailer, excellent idea, which I unashamedly copied for my Track CT.
We did an outback trip last year & came back with a stone blasted trailer, did a very similar trip this year, unmarked!

Thanks for that. will have a look. I know what you mean re the sand blasted look. Saw some trailers reportedly only several months old that looked very 2nd hand. Such a big investment I would like to keep ours looking reasonable for as long as possible.

My thinking is to let the stones "be free" - deflect them away from the trailer - this is what most pro guards are designed to do - the stones come through from the car, and either go under the trailer, or strike an angled mesh / solid panel or whatever, to send them on their way ! Needless to say we need to slow right down for oncoming vehicles. Whatever the guarding, the rear window should be covered too. One small, feral stone can do it - we will be using some plastic core-flute for the next trip (the stuff they screen print those real estate signs on - etc). - a plastic version of the fluted cardboard box material.

Gotta agree with Banjo,send the stones on their way.We have a simple tube frame{removable} on the front of our trailer with 2 truck mudflaps mounted on it at a slight angle.Sends the stones down and sideways,takes the speed out of them quick smart,and the mudflaps are as tough as.

Sounds like i'm on the right track now. Am thinking of a combo of both. Using a truck mudflap hanging off the cruiser as well should help. This may be obvious but do you just tape the coreflute on with duct tape or similar.

k1w1,go to a local truck centre for your mudflaps,got mine for $5 each. Alot of new truck places remove the originals and put their own ones on which have their company logo.The originals are virtually new when removed which was the case with ours.

Hi Alan

last year weused the big truck mudflap thing on our trip, this year we did not. We got a stoneguard from Tambo campers and fitted it to the trakshak, and ideally we'd like to make something similar to the Adeventure Camper Trailers sling type of stone guard, We also used cardboard taped to the rear window as protection from flying stones....

Hi Alan,

We've got the Adventure Campers stone guard which runs under the A-frame of the Silhouette. It has been 100% effective at stopping damage to the front of the camper and to the rear of the truck. We got it through Outbound 4wd Camping Adventures in Ballarat and they even took the time to modify it to suit our set-up.

Hey Wombat
Thanks for the link. It sure looks effective. Might give them a ring and discuss further. In Townsville at the moment. probably be down south around xmas/new year so may get to go and see them then.

IMHO a Stone Guard on the A-frame of a trailer or caravan does little more than provide some level of protection to the object being towed.

All have some sort of frame to support the shadecloth and if a stone bounces off the frame it can still be projected forward into the window (or tailgate) of the vehicle.

The only positive form of protection is cardboard or the acrylic type of barrier.

Cardboard is cheap, but is only worthwhile in fine weather and of course you cannot see through it.

I have also invested in Obie' Outback Window Saver and would recommend it but for one problem. After 6 months or so the weather will affect the adhesive to the extent that the velcro strips will lift, or at a minimum look bleep house due to "rippling".

I am going to replace or reattach mine by using silastic as an adhesive to see if this works better.

Overall, the best solution is a combination of all three. A Stone-guard, a full width "mudflap" and the Window Saver.

P.S. I have also tried a trampoline as used by "black toppers" and they are absolutely useless as soon as you come across MUD. Not worth the effort IMO.
