Great news w11a! Since it sounds like you'll be new to gmk's here's a couple pointers. Setting modular houses can be a muddy enterprise. If you end up in a big mudhole and are trying to get out, don't swing the steering side to side like you would with a wheel loader or articulated tractor, the steering arms and A-arms won't take the strain, especially if you have counterweight mounted. If you lock up all of the differentials, make sure you stay straight when you hit dry ground, the driveshafts won't take that either. When you're on unlevel gravel or dirt, the suspension systems make it easy to spin the tires. When the wheel spins, don't panic and slam on the brakes, that also takes out drivelines. You can instead just back off the throttle and hit the suspension button up and down and it will make the spinning wheel travel down, giving it traction. Remember to lock the suspension before going up on outriggers. Also mod houses are always soft around the foundations, don't get too close to the basement walls, and use big outrigger cribbing, you don't want to crack the walls, or worse yet end up in the basement. The suspension makes it easy to set up on unlevel ground, let us know how it goes. If you have any other questions, ask away! Someone here will know the answer.
