Hi Luthy,
I almost thought I was looking at my white MY14 Colorado when I saw this, as I also have a Rola roof basket on top, a separate rack on the canopy and an awning on the side (I even have a short awning I could fit on the rear :)). I'm interested on how you find running the 285/75 tyres? My past experience is there would be a noticeable loss in acceleration and some fuel economy penalty, compared to factory spec. Plus all the exterior add-on's add to fuel economy loss. Just wondering whether you had a chance to compare performance and fuel economy in factory spec. verses how your Colorado is now? I went up one size in tyres to 245/75 (verses factory spec. 245/70) on mine. Hope the Colorado is still going well for you!

Hey Collie18,

Yeah the 285's have made a noticeable difference in acceleration but I dont really mind to much as they have a fair bit of poke at stock form. Would I do the 285's again? Yes definitely but I like the added height this affords me. If I was to build it more for touring I would definitely leave them at 265's. I run at about 12.8klm/100 but I have a fair bit of stuff hauling in it. If I took the roof cages off the fuel usage goes down a fair bit actually. Mate loving the Colorado..... havent had any big problems with it and it's great to drive. I'm just upgrading the brakes this week to help it stop a lil better with the bigger rubber and then I will get remap to switch the egr system off and a dyno tune.

Glad you like me truck!
