I just got back from a long trip with the truck...2000 miles give our take. Make yourselves a travel trash can. I used the largest cereal tupperware from walmart, and put grocery bags in it. Toss em at the gas stations and put a new bag up top. keeps stuff tidey and easy to use. I will second the lowering of the spare, meant to do that for mine but forgot...luckily I didn't need too.
Also, what REALLY helped with mine... CLEAN GLASS!! I cleaned all the windows, inside and out with the Stoner's Invisible Glass. Then went over and buffed when all with my Meguiars Hybrid ceramic wax. Had several rain showers pop up and the water just beaded up and rolled off. Made getting a clean windshield super easy and nice. Then we I got home, washing it was super simple and all the crap came right off. Bugs didnt even stick.
