83 359 pete good idea/bad idea-good bad idea

yeah its going to all get dyna matted as well as insulated. i put a bunch of that stuff in my mack and it made a noticeable difference.

 

My W900A had like a 1/4" of fiberglass insulation on the back wall and a bag of attic insulation poured on top of the headliner. Definitely going to seal my cab up nice and tight. Its an old truck but no reason it needs to feel like one lol.

 

made a difference in heat or noise? I considered dynamat for noise reduction but after all the reading I did I wasn't convinced it was worth the expense.....i.e. it might not work as advertised.

 

it made a noticable difference in noise. On my mack I did the doors floors firewall and roof but I didn't do any in the sleeper. I can now hear the radio about 10 numbers lower on volume than I could before. It seemed to slightly help with insulation as well. There's other brands besides dynamat that are a bit less expensive. Thinking of trying one of the other brands o the Pete but I plan on covering everything I can with that stuff while the interior is still completely removed

 

Hmmmm. Maybe I need to go that route then. Hearing is worth it

 

The 379 cab is wider. The 359 and 379 flat roof use the same cab lights. The ultra cab uses a different light with a different curve.

 

Has anybody tried roll on bed liner instead of dyna mat?

 

i ordered some

Noice 80 mil car sound deadening

has good reviews almost half the cost of dynamat ill let you guys know what i think of it. i got 36 square feet im sure ill need more but was around $70

No they do not.......been there done that with peterbilt original lights. I own a non ultra cab 379 and 2 359's the lights do not interchange. Wider cab doesn't have squat to do with it

 

Lowes or home depot carry a sticky backed foam roll insulation with a silver foil face. Ive used it in my international crew cab to cut down on solar heating from such a huge roof and it worked pretty well. The R value isnt impressive but the solar rejection was.
