Bobby,

I have the Beseler 8x10 conversion on a 45MCRX chassis and while it works, that chassis was never designed to have that much weight hanging that far out from the upright. It is VERY prone to vibration and alignment is a constant battle. I have a 45V-XL chassis and will be transitioning the head to it when I get some time. The 45V is a very stout rig and can easily handle the 8x10 head.
