GBL , I have to let you know that you are not the only guy to do that, and i am not a rookie either, but sure felt like it at the time. Same deal repositioning a 21 foot glasply on the ramp at port angeles, during their derby. Just set the back end down on the concrete, got out of the truck like it was no big deal, hooked up the winch, cranked her back on then backed her down a little straighter this time, told my buddy to unhook the boat from the trailor (no it doesnt get worse) backed down quickly, popped the brakes and slide her right in. Sure was glad to go and park that truck
