This one may seem novice or silly, so bear with me please.

Is there a maximum height that you can raise a wheel(such as when rolling over something or when jacking) before something bad happens? Can the frame be subject to twisting under such a maneuver? Reason I ask is, I did a dumb thing today and backed over my wooden wheel block(Its a piece of one of those wooden landscape timbers) when backing out of the garage. The rear of the truck on the left side went up about 3/12 inches, then down before I realized what had happened. Fortunately I had plenty of interior height and did not hit the top bow against the garage door.

Your frame is designed to flex (i.e. twist) under the conditions you describe. Running over your stop block did no damage whatsoever. Rock-crawlers abuse their trucks MUCH more severely than that with no problems.

If you get both wheels on the same side high enough that your center of gravity shifts to the outside of the tires on the ground, your truck will tip over...guaranteed! However, you won't be able to do that with a jack.

That said, I don't think you have a problem. Enjoy your truck!

Go buy an M-715 I actually got stuck by backing one wheel over the borrow pit and suspending a tire in the air. The frame and suspensions do not flex. Tom

Nothing to worry about, Nick-climbing over your chock block isn't any more severe than the height change you'd encounter in climbing your M over a curb....

Hey Nick the M37 has one of the best frames ever. Flexible and strong. I know a couple of guys here that regularly off road on really rocky rough back roads and no problems.

Yeah I didn't really think it would be a problem, but just felt better to ask....I was actually more concerned wit hthe fact that I could have hit the top bow against the open garage door, but from measuring found that I still had plenty of room.

I'm glad you asked too, nickathome, I run over my park block all the time. But that's better than when I would pull into my garage with my WC52 with the rear bows on, had to replace the first row three times, ( embarrasing )
