Does anybody know what you do if you have a sewn-in campervan awning groundsheet, but the campsite states that awnings should have 'aerotex' groundsheets in awnings?
Stick some aerotex under it. Its a nonesense is all this groundsheet business. The only way you are going to keep a pitch half-healthy, is not have it covered, by anything, from time to time. Grass needs light and air, and its not going to get it even if a tent/awning had no groundsheet whatsoever. As there'd still be stuff all over it + the foot traffic.
Sites should have enough pitches to allow for this at peak times, its the only way to avoid yellowed sludgy patches all over.
True as above, that is why the best ACSI campsites all over europe don't give a toss, its only in this country that some bird brain cites some rules from god knows where and they all have to implement them, say no more.
Do campervan awnings have sewn in ground sheets? I've never seen one. If you mean the sleeping compartment hung inside the awning, they are ok, its the ground sheet in the main part of the awning that needs to be breathable.
Yes, several of them do have sewn-in groundsheets. I've been shopping around on the web for Campervan Awnings and the two I am considering both have sewn-in groundsheets to the whole awning, not just the sleeping area. The Outdoor Revolution Navigator Kombi and the Khyam Driveaway XC both have sewn-in groundsheets.
