DO you have trailer braking issues?
Does that FOX have Dexter Nev-R Adjust Brakes....that self adjust when moving forward and braking?
Disc Brakes do provide better braking power BUT drum brakes will stop effectively when properly adjusted.
DO you FT and therefore the disc brake upgrade/cost is truly beneficial OR just camp seasonally and WANT disc brakes?
We FTd 7 yrs...towing 14K 5vr (scaled weight) with drum brakes and NEVER had a situation where I felt the braking was lacking...slow stop, quick stops and few emergency full on hard braking.
