The generally recommended process, and one that I've also followed, is to fit, drill, and cleco the pieces in the order shown in the build manual. The sequence is pretty important because it helps to assure all the correct overlaps and fits. Then Sharkhide (in your case), then permanently bond and rivet. Don't be in a hurry to rivet panels though. F panels on the front yes, but then after that, look at brake lines, fuel lines, electrical harness (mainly the rear harness) installations before installing permanently. Hope that helps a little.
Congrats on your pickup. Have made that trip a couple times my self (including the Canada route) and it's pretty exciting. We're practically neighbors, so give me a shout with questions or if you need any help.
