Coop, afraid I won't be able to letter it at all! The laws here say it can't be lettered unless it's registered and insured as commercial. I've heard that I will probably have to put on "not for hire" on it too. If so, I'll do that on some magnetic sheet so it's easily removable.
So because of this, it's going to be the "brand new" wrecker look before old Vic lettered it.
RINC, first pics is of the DG5 mirrors I considered putting on. These are really big and would be great for towing but mine won't see much work. (thanks to the laws) Wouldn't mind doing a little towing to recoup some of my investment but heard it's a $3,000 dollar fine if I'm caught towing without all the permits, licenses and insurance!
Second pic shows what the flyswatter type long arm mirrors look like. (not my truck, just for reference)
