Stone shield

If you want to protect the van from stones you'll need more than the under A Frame version.

There are heaps of versions around most of em have something like Shade Cloth stretched not too tightly over a framework.

This stops the stones bouncing off the fabric and into your back windows as well

George,
take a look at this.

I have one behind a Prado and in front of a Jayco Eagle Outback. All good. Simple and straight forward. They are a good mob to deal with. I am not affiliated, etc...

Hi George. This unit belongs to my brother and has travelled around 30000Km so far. At least half on dirt with no stone damage to van or car. It is heavy shadecloth doubled over a frame to suit the width of the van. Bob.Image Could Not Be FoundImage Could Not Be FoundImage Could Not Be Found

If you are not too fussy about appearance, a piece of concrete slab arc mesh with shade cloth over it works fine.
You can cut a hole on the mesh to allow the A frame to protrude so it hangs under the A frame as well as over for protection, and a couple of occy straps will hold it in place.
Only takes a few minutes to make, very few dollars, takes 2 minutes to fit or remove, and you can modify the shape and size easily to suit your caravan if you wanted to make a more professional looking stone guard.
Ours has lasted 25 000 k's so far over 3 years, but the shade cloth needs replacing.
We held the shade cloth on with the wire mesh fence circle thingies that squeeze on with special pliers.
Cost about $10 including the fence pliers and clips, and we have had no stone chips, broken rear window, or tail lights yet.
Cheers

I just tossed one together George - used pvc conduit and shadecloth - in my view, not worth making something "el-swisho" because it gets very dirty at times and damaged eventually. With the vehicle and van hitched up, I simply measured the area in between the van's front and the car and got some shadecloth to suit.
I made cutouts to suit the various objects on top of the draw bar area (gas etc.) To hold it all, I have a piece of PVC conduit crossways for and aft to hold the cloth - the cloth is fastened to the tubes with a host of small cheap cable ties.
The PVC tubes are tied to points on the van and car with ockies to keep the whole thing elastic, for turning etc. I store it in the poles tube built into the van - Whatever - has worked ok for us so far. Used the same setup on our hardfloor camper trailer too. BTW - it could of course be made to go under the draw bar, but would get damaged in no time at all as I see it, on those long gravel roads.

Hi George

few of them here: stone guards and more to give you some ideas on where to start. Just scroll down and you should find them, cheers....
