I owned a Bret Herndon Aerolid from November of 2014 until August of 2015 for my 2014 Ford F-150 XLT with a 6.5 foot bed. I sold it in exchange for a G-4 Bed Cover because we had bought a 5th Wheel trailer and this gave us much better access to the bed of the truck. I have been keeping fuel data on the truck since 2014 in its various permutations. I got curious and started wondering what the fuel log data could tell me about the performance of the Aerolid versus the G-4 Bed Cover. I had to try to extract data by looking for comparable log entries. At first I settled on all numbers above 18 mpg to get highway miles .

The numbers were real close with the Aerolid averaging 18.05 mpg over the Bed Cover 17.79 mpg for a 0.08% difference.

However including my data for fuel runs down to 17 mpg reversed the slight advantage that the Aerolid had. Aerolid over 6,469 miles used 361.7 gals of fuel for a 17.88 mpg composite average. The G-4 Bed Cover over 5,076 miles used 281.1 gals of fuel for a 18.05 mpg average.

Post Script: There is no mass advantage to either configuration. The Aerolid mass was about 200 LBS and the G-4 Bed Cover while lighter covers a 5th wheel hitch assembly that weighs about 200 pounds.
