Thanks blitzk. I do like the looks of this combo but Joe is 100% correct. It just wouldn't work in my play area. The roads are all gravel and fairly steep too! It would be stuck everywhere, not to mention that the roads aren't very smooth or flat so it would probably fall over while dumping. Even at the shows we attend we always end up making an offroad environment so it wouldn't work there either.
I did have fun towing it around my shop floor yesterday though!
