We spend a lot of time on two tracks in Colorado and Utah in our Tiger. I'm always amazed at how far out people will take their 2wd C's and B's. Generally speaking good driving technique, experience and common sense will take you a long way......But, when bad decisions and mother nature kicks in a good set of tires, air compressor (airing down), traction devices (chains, mats, etc...) shovel, recover strap, quality recovery points (front and rear) and some hardwork will take you a long way if stuck. After that, a locker with chains and throttle control will take you a long way.....By the time your into lifts, winchs and 4wd your really going places that will challenge any rig and driver.
Most of what we've seen has been sinking in mud, mud/snow slide-offs on slight inclines and high center stuck (approach/departure length stucks). In the end and while exploring, and since AAA won't recover off-road, keep an extra $1000 around for off-road recovery! Cheers and have fun!
(Off-road RV secret......foam in your cabinets to absorb rattles, small bungees on all cabinet doors, drawers and oven door, Nothing on the counter/floor........RV's are noisy on the highway, just wait till you get it on the trail, it'll sound like it's coming apart! Also, due to chassis flex check all seams when done to make sure you haven't popped a seam and a leak or structural damage has occurred....mmmmmm.....life off-road.)
