Ok results are in. keep in mind not 100 accurate but as close as I could get
keep in mind my last trip same RV but from west to east ( I-40 I-70) was 7.9 MPG avg and truck gets 15.7 mpg avg empty
1st day ......................................................
leave Harrisburg PA up to I-10 ( north to ) mild hills and mountains
10.1 MPG at 55 to 65 MPH
once on I-80 headed west at 65 to 75 MPH ( 1800 RPM ) 8.6 to 9.1 MPG
2nd day..........................................................
Ohia to Illinois 8.6 MPG ( flat highway ) ( 65-73 MPH )
3rd day..........................................................
Omaha to Denver ( well Limon area east of Denver ) 8.3 MPG ( flat highway but last half starting elevation increase ) 73 MPH avg ish 8.3 MPG once I hit 4000 ft above sea level
4th day.........................................................
eastern CO south to colorado springs to Westcliffe ( 6k to 8k above sea level ) truck not overheating but running hot to maintain 60 to 65 oil temp up to 240 ish , water bouncing off of 3/4 on gauge, exhaust gas 1500 to 1800, could not get below 1200 when backing off, heavy headwind none stop 8.0 MPG.
5th day...........................................................
NO RV, south to PHX AZ, average back to 15.8 MPG at high 75 MPH
..................................................................
Final thoughts, Air deflector did work, but not enough to justify the cost. I feel I got 0.5 to 0.8 MPG gain, as for bugs bottom half of the front of the RV was clean, top half was covered in bugs.
So the product looked great and worked little, if it was 150$ or less ( what it should cost ) I would keep it. But for the $ I spent the payback time was too great. return the product through Amazon for a full refund so nothing lost.
