In the photo you have a small mounting bracket with a hole in it. You will also have one near the rear of the van. You may [hopefully] have one midway, or something that looks like this that my rear cycle carrier was hooked onto on a previous van:-

If you posses either of these then you should be able to fabricate out of a spoon, strip of bent metal etc something to raise the bag up so it does not foul the door. You will probably not get a 100% solution but you will make life a lot easier.

Where abouts do you live as somebody may have a Caravanstore you could slide in to check before buying, or an Isabella to also try for fit.

He's posh Roger, the 3rd/centre pole is an optional extra.
Most poor folk pull a cord through the hole to make a V shape on the front for run-off. I have heard if do you want a pole an adjustable washing line pole is a good alternative.

Colin

Yep, quite right Colin. A aluminium telescopic washing line prop from Wilkos., £3.00. Buy two. You never know when a pole will come in handy. No, a pole, not a Pole. .
Also Eribanut, you can't use a telescopic pole for star gazing.

I think the easiest way to price a booking is for the pitch. You should be able to do use your pitch and the site facilities as you [reasonably and sociably] wish. Some facilities you will not require whilst others you will. Your needs will differ from others. You may have two adults, an awning or a canopy. Possibly a dog or two. Your use of showers will differ from others. electricity use may be more or less than the average. Do you use/need a tv hook-up. Is wi-fi your thing..Will you use the shop or bar. How can you work out all of these variables? One price, job done, no arguments.

Cor, this next statement makes me appear to be very 21st Century. I now have a 4G phone. You know the ones that do everything apart from phone. However I've only recently been informed that my very cheap contract includes a "bundle" of goodies like free phone calls, Emails and Free Roaming up to a certain limit.
Up until now I've not been taking advantage of these and because they are a monthly use it or lose it, I've been giving it a hammering.
I think that's what it is anyway

I think you misread my tongue in cheek comment. I don't pay over the odds for anything. We only go for the cheapest contract and (as far as we are aware) £8.50 a month (minus £3.00 if you accept ads) is pretty cheap,yet it still seems to have these free add ons.
Meanwhile, back to the Fiamma v Omnistore debate...........
