I recently purchased my competition in a small town. The wash has 4 selfserve bays and 1 automatic bay. The automatic is an old superwash and the bay appears to small to put another automatic in, and my other wash has a new razor a block away so its kind of pointless to upgrade this automatic. I was thinking of tearing the automatic bay off and just make it a outside bay with higher pressure for large trucks and such. There is no place in the area to wash semi sized vehicles. I was thinking of maybe even having an undercarriage wash they could drive over since it is already there. For those of you who have outside bays, are they worth while and are there any drawbacks to an outside bay?
