It came with ours Lance 1161 side entry and side awning...used once in rain situation only because it was already deployed when it started to rain. Have used a number of times when wanted more privacy as I have made an enclosure for it out of cloth shower curtains..no pics available...BUT honestly I would not order one up front until you figure your TCing use characteristics...it can always be added.
BTW, rolling them up wet is not a good idea, mine has the auto closing cover when stowed...totally protected. NOW slide awning is a different animal...I'd get one and it would be a protected type, may have to get that aftermarket as well, as I do not think the TC OEM would install the higher grade or even offer it.
