Rampage,
One thing you might want to know about before you start taking long trips. The rear boggie axle is the weak point on the Imp's. I know of a few Imps that have broken them off and at the worst times, as mine was before I bought it.
Here is a photo of mine and what I did to make them stronger. I drove a round heavy wall pipe all the way though both the front and real axle tubes, then drilled and bolted each outside end. That allows a bit of flex, but will not let it go too far out of "Straight".
They are a bit of a hassle to drive in because the fit is tight, but if you use a flash lite and look into the square tube, you will see a weld line on the inside, if you grind a flat spot on the round pipe to match it, it will make the sledge work a lot easier.
