Ha! I had vortex generators on my last airplane. Never thought I'd see them on a motorhome! I used them to make my low speed handling better in the air. You're using them to make high speed handling better. Cool!

We're HH members. Just signed up this year but have stayed at HH more than other campgrounds. But then we just bought our first RV so we haven't stayed much of anywhere yet! We've stayed at two wineries and love both places even though we don't drink wine. We still try to buy something at their gift shop as a thank you. One of the wineries even had 3 spots with water and electric! No sewer and no dump station though. We love HH!
