Yes totally legal.
Yes of course but you will jave to pay toll fpr both cars
Yes you can. I have seen many people town their cars behind their RV.
I would Definitely check regulations regarding towing. Tho with the construction i encountered you might want to consider another route IF its not done
The only prohibition I see in the Green Book is "Towed vehicles which are insecurely hitched." You'll probably be required to tow it on a trailer or in some standard way.
Yes if it is on a proper trailer or you have the proper permits for the tow truck
Yes
I've seen multiple vehicles being towed on GW.
