Thread: rocktamer style flaps for D4

Hi Andrew,

I went through the same exercise and did a fair bit of research, including asking other van owners what they do.

The main issue with the full length, bumper to ground Rocktamer type mudflaps, seems to be the restriction of airflow under the vehicle, and a resulting increase in the operating temp of some components. There also seems to be a good case for rocks still getting through to the trailer or van, and flicking back onto the rear window. The rear window was my main worry. I think the last price I saw was $1600.00.

I have just ordered a Stonestomper. It uses a suspended trampolene between the vehicle and van/trailer, and has a full length floppy mudflap, but it does not go down to the ground level.

Check them out on the web. When it arrives I will post some pics here.

Plus a stonestomper restricts the amount of dust that covers your camper as most of it goes straight under the trailer, same goes for restricting mud if your driving on wet tracks. They are a good thing, not cheap but a good thing.

Would have been easy on the D2 as I have a DIY steel bumper.Anybody made or used a set on a D3 or D4????,to tell the truth havent even poked my head under there yet to see whats behind the plastic bumper.
I have a brand new pair of white truck mudflaps for the job,SOMEWHERE in the shed

Andy, there is a very goodstrong subframe that supports the rear bumper in behind the plastic as well as the towbar, you won't have any trouble finding something to hang stuff off.

Hi Admiral, I am in the process of getting a stone stomper as well. Talking to Christian from stone stomper it may require a clever mount for the back of the D4 because the standard brackets do not fit the towbar tongue. So I will be interested to see what the solution is.

There are more examples, can't find them all ATM.

Edited: sorry LandyAndy, meant to post this in your other mudflaps thread

Hello Andrew,

I fitted a Stone Stomper to my D4 and caravan before our Central Australia Trip.
It did a good job of protecting the draw bar, front of the caravan and rear window of the D4. It does not stop stones striking the under side of the caravan from where the Stone Stomper is attached. I found stone damage from about 1m after where the Stone Stomper is attached to the caravan.
I also found that small stones/sand/mud would still strike the front top corners of the caravan. I think the low pressure/vacuum at the rear of the D4 was drawing the stones/sand/mud in towards the caravan.

I fitted a slightly longer Towbar Tongue so the horizontal bar bracket fitted correctly.

I still think it did a great job and very happy with fitting the Sone Stomper.

????? I just received mine a few days agao and after reading that figured I better fit it now and see.
The L bracket appears smaller than those in advertising pictures. The L bracket is tight and the bar pushes against the plastic of the bumper. I'll have to drop the van on it and back sure there is room for the hitch tho. Will advise tomorrow.
If not, I'll just use a longer shank tow hitch on the car and get Christian to send another bracket

I have a variation on the L shaped mount bracket, as I am also using the McHitch auto coupler. I have asked Christian for a slightly wider base on the bracket, and locating tabs so it won't twist when mounted between the McHitch and towlug. ( the attached pic is my original lug )NAY_3143.jpg

I have changed the lug to a HR 21124 same as NTB, as the other lugs take the coupling too far away from the hitch receiver. Even the 21124 is 15 odd mm further away from the receiver than the LR recommended maximum.

I can tell you the whole bloody exercise is just getting too damn complicated. Hope it works after all of this.

I think we are also hijacking this thread. Sorry about that.
