Ted;
I have a 2000 Volvo S70, that has an air dam across the front, so that when I load on the Roadmaster 2000-1 dolly, I need to put a piece of 2x8 under the end of the ramp, just to avoid what you have described. Works well. I need to carry the 2x8 to put under the jacks on the Beaver, so nothing extra involved.
