Never been to Alberta... on that note....
Check with Carli and Thuren as I suggested. They are pricey, but, you DO get what you pay for. If you want something that will handle the fire roads, and the woods...
I pull plenty of logs with mine..... a hydraulic winch, and 35s.... All, I need. Good tires, good traction. Simple, and reliable are important.
Not telling you how to build your rig. Just saying... for the extra inch of ground clearance, I dont find it worth the hassle myself. The truck sits plenty high, but, that is just me....
GOOD springs, and GOOD shocks, will make a WORLD of difference in your rig.
Are you running 3.54s? or 4.10s?
