I’m looking to reduce dust and noise in the cab and would like some feedback. I plan on using Spectrum and Damplifier on my bed and engine cowl. Where I am stuck is whether I should buy a Stitchmasters’ Dust Skirt or a set of the Trail Armor dust reducers and coat them in Spectrum and Damplifier. I plan on using a back window; will that be a problem with the Dust Skirt? Both kits appear to attach to the bed. Will I still be able to use that dump feature?
