I ordered a truxedo tonneau for my truck last week from these guys. I specified when I ordered that I did not have the utilitrak system so that they would make sure I got the right install kit. Of course they send me the utilitrak kit and no clamps so I cannot install cover. I have called truckmod and left messages and have e-mailed them several times and have still not heard back from anyone. It has been about 5 days now so I will have to go to a local dealer and buy the clamps I didn't receive for $7 a piece, I think I need 6 of them. Obviously I would not do business with this vendor again.
