I installed Air Tabs on my rig in April before a 7K trip in May and June. I see a significant improvement when being passed by big rigs on the road. Almost cannot tell when I am being passed. Did not have sufficient history with this rig to make a fair determination if fuel mileage increased, but I think it did get better a little bit. Did not see any improvement in dirt on rear of MH or on toad...............just my observations.................ronspradley
