I came across this website where you can buy towing protect covers. I am new to towing (still waiting for the trailer pick up), but this looks like a good idea to me - do not have to install mud flaps, do not have to worry about the bugs, etc.
Protec Covers - Pro-Tec Covers. Caravan Covers, Motorhome Covers and Tailored Covers for Vehicles
Obviously, this is a supplier from the UK. Are similar products available in the US? Do you think that this is a good idea / bad idea to use this product while towing?
