Hi: P. Raz... I've seen those "Legal documents" before. Sorta amts. to a gag order with other conditions!!! We had to sign one to get some warranty to replace 25yr. shingles that didn't make 15. 1000's of others bought them too, but we ended up better'n most due in part by the local roofer who did the replacing. The mfg. wanted me to send them a shingle off the roof as well as pic's but I cleaned the crumbs out of the eavestroughs and sent them in a large ziploc bag. My guess was that the package looked suspicous enough to garner some attention.
Too bad it had to come to an impass with your trailer. I went to CanAm RV near here, to see a new 1500 Trill. from Mattman they had in stock and never made it past the door of the trailer.
