I have had gauges on the pillar, and in a dash mount in my other Dodge's. I am going to put gauges in this 2001, but was thinking of hiding them in the ashtray. Anyone tried this? If two will fit I will use separate boost and pyro, if not I could get a single combo gauge. Just a thought. Also, has anyone found a good setup for the fuel pressure gauges. I know folks were having trouble with the autometer electric, and I dont want a diesel line in the cab. Any thoughts?
