The more I think about it the more I keep coming back to the thought that Wally himself was constantly innovating and changing the trailers to meet the needs of the people who used them. He encouraged them to tell him what needed to be altered to make them as functional and enjoyable as they could be. Heck, in thecatsandI's latest pictures from the factory there's Wally's anodized trailer - quite a variance from the norm. And you could literally order a very customized trailer right from the factory if the standard build did not meet your desires and it is only the factory's desire to standardize production to keep costs and other aspects controlled that has limited this ability. So I guess I'm firmly in the campground that's filled with the modifieds. It's not the sameness of them that makes them so neat, it is the unique and often subtle alterations owners have made over the years to make them functionally superior to the original that makes each one a pleasure to see IMHO.
