After going through a half dozen custom trailer shops around central Florida and receiving lukewarm responses at best, I finally found one that was very friendly and I could communicate my ideas in a very friendly back and forth atmosphere. While the others were professional and all, they felt more like a "yah, we build trailers, just send us a drawing, money, and we'll build it" without even really understanding the purpose or helping me understand what's neeeded.
The company I found that was very nice but very professional was SlingThing Trailers in Punta Gorda and the persons name was Heather. It quickly became a friendly conversation, instead of the quick "just tell me what you want and give me money" attitude. I don't think they have a regular shop, but hey if the trailer is well built, it doesn't matter if they do it with a magic wand, LOL.
Anyway, just thought I'd put this out there and maybe somebody else won't have to put up with the hunt I did.
