It was me you called earlier today to arrange a visit. I didn't think of it at the time, but Jim Lieb here in Santa Cruz has a 17B, and it was his trailer I visited just before i bought my previous trailer, a 17B. I can't find his phone number, but the folks at ETI should be able to help, or you could PM him through the forum. You could see both a 17B and and a 19.
