X2- That's one fantastic guy, company and piece of equipment! I have somewhere around 25K miles on mine now and used it to tow from GA to Anchorage on some pretty tough roads, and back-- and have run up and down the eastern US quite a bit. It is really stout!
I have manged to wear a good bit of the paint off mine in a bit over 2 years from road dirt, gravel debris so I'll be repainting it this year. I did add a break away switch- took about 15 minutes.
I know you are going to be very pleased with your new dolly!
