I have a 2012 F350 dually I pull a 40' fifth wheel RV with. I purchased a Viair 300P portable compressor to use to inflate air hitch and air pinbox on camper. I would like to use a 7 way plug adapter to get power from rear, instead of connecting to battery way up front. Problem is, Ford only uses a 25 amp fuse for this circuit and compressor may draw a max of 30 amps. Do I dare change that 25 amp out to a 30 amp in the distribution box under the hood or do I need to find another idea ?
