Hard to belive I did most of the sound abatement work 3 years ago.
My F-700 (The U-RV) has always been a noisy rascal on the highway. you know the typical med duty truck no headliner and no cab insulation other than what is under the rubber floor mat. Not really designed for driver comfort for extended drive times.
Three years ago I decided to try to fix mine. I bought a few boxes of Dynamat Extreme. I covered the headliner back wall of the cab including every inch of the back window. since I had the passenger seat out I covered a lot of the floor. I even covered the entire back wall of the cab in carpet over top of the dynamat.
This did make a real difference. however there was still a LOT of heat (No Cab AC) in the cab in july almost more than you would expect.
I believe i have found the reason(s) for all the heat getting in the cab.
1 the clutch rod boot is damaged. (2 X 3 inch hole in floor)
2 Gas pedal boot is bad (not nearly as bad as the clutch rod. 1 X 3 inch hole)
3 the big reason,... is the dog house is loose. I mean REALLY loose. someone had it out in the past and reinstalled it with 2 or 3 spot welds.
of course the welds didn't hold so I used some steel strapping and riveted it back. and of course I had to seal it all up with some seam sealer.
From 3 years ago It seem I still had a box full box of Dynamat
(Saved $60).
So Now I have almost the every square inch of floor covered in Dynamat. and I'm makeing some boots for both the pedals from EPDM Roof rubber. These will be a great help for sure.
The moral of the story is if Your truck had in the past a PTO, You might just have holes in the floor for the PTO shifter and the doghouse might not be sealed down real good.
