I'm ready to pull the trigger on my Duamax Colorado. I met a gentleman a while back pulling a 1685 Lance 96" width trailer. I also plan to purchase same trailer. He was using Dometic Grande Tow Mirrors. He said it worked very well. What do you all think of them? Also debating a Colorado LT vs Z71. I lose safety warning light system with Z71. Love the Rims on Z71. Not sure which tows better suspension wise. Thoughts appreaited.
