Fits really well and is very well made! I was worried because my gas bottles are only 4.5kg so they were a lot narrower than the wide part of the cover, the three straps (and there are additionally three pairs of tie down loops as well) pulls it down nicely. There are also two clever slits along the back edge that locate over the drawbar keeping the cover in place. My jockey wheel fits nicely under the cover, the handle is inline with the top of the gas bottles.
The hitch cover for my caravan has just arrived and I've placed it straight onto the draw bar. It was very easy to attach with the clips underneath allowing for the jocket wheel and stands. I love how it covers the gas bottles too. The purchasing process was very easy and delivery was very efficient. I am yet to experience the effectiveness of the cover but I am very happy with everything so far.
