I hear ya, but chances are slim. One problem is that the shower enclosure sometimes varies with the floor plan - they fit it whatever size works in each layout.
War story: We had a visitor here a year or so ago that needed specific weight info on an RV he liked and hoped to buy. It was several hundred miles away, so he called and asked a sales buy to go out and read or snap a photo of the weight info placard. The guy tried to give him brochure info, then offered his guestimate, but finally agreed to go look. When the sales guy didn't call back for a couple days, the fellow called again and got more promises but still no actual info. Really frustrated that a sales person couldn't be bothered to spend 5 minutes to get the actual data, yet blathered on the phone for 20 minutes to avoid it. Last I heard, he never did get that weight info and I don't know if he made the trip to see for himself. Hope you get better results.
