I have seen some ingenious campers that skirt the CG 'no pop up tent rule' simply by not putting out your awning and putting the EZ-up w/screen right up against your RV under where your awning is.
My camping neighbor did this when he saw screen rooms being allowed but not his EZ-UP. Felt that wasn't fair.
So he rolled up his RV awning and he put that puppy up against the RV under where the awning is just like an RV screen room would be and look like.
CG owner admitted that if it were placed there he really couldn't have a problem with it and allowed them if placed along side your RV from there on in. :C
And if a storm does come up quickly. Just take or knock down the ezup and take cover. At least you know your RV $awning$ is already rolled up and out of harms way.
