I'm not ignoring you.
I am however an idiot!
You said dolly but I was thinking rotisserie which is not here. I have a dolly here (Pascual has made three of them}.
From side to side at the front mounting points is 40.5" center to center. From side to side at the rear is 34.5" center to center. From front to rear mounting points is 66.75". The legs coming up at the front are 12.5" tall and at the rear are 6.5" tall. These are as close as I can get measuring, as my car is still on the dolly.
Would not be a bad idea to extend the rear tires further back as they are a bit rear heavy. However we have loaded them on car trailers several times with no issue.
