I'm wondering what the effect of hard offroading over big rocks is on the trooper. I was away the other week and went up a very rocky and steep mountain (part of the trail was a stream bed) in a chevy pickup 4x4. The person I was with was a little worried about the effects of this rocky trail on the frame of his truck. He used the term, twisting the frame, up such a trail. Since I will be back there with my trooper, I'm wondering, what type of effect can these trails have on the truck? Obviously, parts of the suspension could break, but is this frame twisting thing a possibility?
It is possible if you go barreling through boulders at 30mph. Every time I've off-roaded with experienced off-roaders, we did like 5mph or crawl speed in any situations where the frame could come in contact with rocks and such. I rode over probably 50 boulders down in Uwharrie in July where I scraped the frame/skid-plates, etc against rocks and other items, no damage done to them or the car. I wouldn't worry unless you go speeding over them.
Jakemm made a point in the rodeo section that his rodeo hits the spare and gas tank in deep sand. I've been in moderate sand a couple times in my trooper. Airing down is one thing of course but keeping your speed up, so you don't grind in and sink is another. With the rodeo 4Hi is probably best. With the trooper, TOD vs 4Lo is sometimes a toss-up since you can't always keep speeds much over 30 in 4Lo. Sbcooke also has had alot of exprience in sand.
In deep sand the trooper doesn't drag, but does touch the sand every so often, especially the gas tank. The first generation explorers are like a whirling dirvesh, dragging along the beach. The troopers just clear the sand(while driving). While parked it looks like there is a lot more clearance. I am thinking about adding OME springs, for load carrying and ride purposes, but that will also lift the body up an inch or so higher.
With a solid axle, only bigger tires will lift the differential higher from the ground, but body lift could/would help. 4-lo has a lot of gear resistance (i.e. come off the gas and you slow down) over 25-30, I think that is why people (including me) feel more comfortable at that speed.
