Don't overlook the brakes on your FW. Many whine and complain about junk Ch*nese tires and other Ch*nese made stuff in our RVs, but don't seem to think twice about the brakes (or bearings) made over there. Besides the drums, shoes and parts inside the drums, wiring can sometimes be bad. The only way to ensure they're in good condition is to pull the drums for an inspection, not doing a lockup breaking test.
Don't know how old your FW is, but even brakes or bearings on a new FW or TT can be trouble. Another but related topic, if you haven't it might be time for a bearing inspection & repack.
Not the same, but when we had our old F150, my BIL who owns an auto parts shop sold us some ceramic pads and vented rotors. Huge improvement! Our F250 has the original pads and rotors and may upgrade them at some point but work well as is.
