A very generous person saw a wind deflector at a thrift shop and picked it up for me. Unfortunately I cannot accept it, so am helping him pass it on to one of my viewers who might appreciate it. I did a video called "Can an Old Snowboard Wind Deflector Improve Gas Mileage while Towing?" https://youtu.be/9bvaEYFTKS4 a couple of years ago, so can attest that they definitely can save you gas mileage while towing a camper or trailer.
Anyone interested? It is located in New Brunswick Canada, and the price is very low. Please just send a message to this post and I will pass your email onto Stephen. Don't worry, no email addresses will show up in the comments. Thanks! SP
