trail_runner4r and billiebob,
I currently have a home base in Colorado Springs. I drive a 2013 Silverado 1500 extended cab with a 6.75ft bed. It is stock height as of now. I recently went full time status and have been on easy to moderate trails and forrest service roads. I will be getting 285/70r18 tires to replace the 265/65r18 ones. I will also be doing a 2” BDS leveling kit at the same time. I guess, realistically, I would be spending 65-75% of the time off-road.
I plan on eventually having a 4”BDS coil over with remote reservoir lift, but my budget is going to getting other work done on my truck now. Lol, I did some damage to the passenger front and rear door along with the rocker panel. I can get both tires for about the same price so the budget for the tires now isn’t a big deal.
A bit off -topic (mods forgive), but I have a 2014 GMC Sierra of the same configuration and have a bed cap on as well. Basically the same truck. If you do go with the level kit, you may want to make sure to put some blocks in the rear. I leveled mine and with the Leer cap and some equipment in the back, it can look as though its leaning back on its haunches a bit.
To keep it on-topic, I'm also eyeing the Falken WildPeaks, so I'll be watching the replies here
