Thanks for the state to state heads up on dolly's, I have never been ask for any info. on a dolled(sp? is that right??) car and I have had a safety check by the staties once. My insurance Co. says the dolly and or trailer are extension of the car and thus covered, that is in Colorado to the best of my knowledge. Back to trailers..I am not a wood deck fan, but I did have good luck with a local mill making me 2" by 6" by 18' cottonwood lumber that I decked my 18' with. That is some strong wood but you have to put it down the day you get it from the mill, cost me 100$. I like a 18' to 20' trailer a bit on the high side so that you have a 8' wide deck, great for farm junk.
