Have posted this before but once again: vacuum wipers have an advantage over electric IF DONE RIGHT. First, go to your local pick-a-part and get the electric vacuum pump from a Mercedes diesel for 10 bucks or less (it's behind the spare tire). This can be mounted anywhere in the truck so even the best show judge doesn't know it exists if you use a little ingenuity. Where your friends truck may have a 2 or even 3 speed electric wiper you will have one with 100+ and it will work uphill pulling a loaded trailer and with the foot feed on the floor. You don't need intermittant wipers since you can adjust the speed to provide one sweep at any time interval you desire.
