Pardon the uneducated.

Are there any difference in these 30k rock buggies and the buggies those really high sand hills? Looks like different tires and maybe a different gearbox?

Just curious. I've been taking some interest in the buggy type crawlers.
 
Definately different gears. Suspension will probably be close (you need alot of travel both ways) but from what I have seen, the sandhill rigs are set up for almost equal drop and compression on both sides where rock buggies need to be more set up for each corner being able to compress or droop more than the other side. Also more protection from the terrain. I cant see sand crushing a diff cover in on the ring gear where a rock wont even think twice.
 
high power and high wheel speed. Sand buggies are built to get the wheel speed up fast.

crawlers are built for torque. 5.13ish gears, low range crawl boxes. sometimes even reduction boxes at the hubs.
 
Weight is also placed at different ends (motor). Sand rig is light in front and carries the tires just barley touching enough to steer, also has cutting brakes usually. Looks similar but not the same. Major horse power so they can stay on top of the sand and not dig in.
 
Okay......when you are saying sand hill climbers are you talking about the guys out at the dunes messing around or the guys in iceland doing the crazy hill climbing or.....??????
