OK I'll be good and introduce myself :)

Andy, from southern Alberta (Canada eh!) - found you guys looking for a DIY VG design, now too many more questions without answers :)

Welcome to the site Andy. What were you planning on slapping VGs on?

Ran airtabs on my last RV - mostly for the handling... ended up with an unplanned delay before my next camping trip - no time to order (I hope) - so was going to DIY a set...

but then I got researching on where to use them, and realized there's a big mess with towing 5th wheels and the aerodynamics (and better fuel economy means longer trips... I need a trip to the coast ;) ). So now I have a thread in aerodynamics... :D
