I fill my tires AND inside entire cabin area with Helium.
The RV now scales out a 2500# and I get 39 mpg! But on windy days (and empty tanks of coarse) it will leave the road if you go to fast and float to the next mile marker. LOL
The Upside is the tires last alot longer.
Down side is we sound like chipmunks going down the road. LOL
