Over the years, I have shown you many “Mac Dash” installs. Mac McNeal has been building custom dashes for the GMC Motorhome longer than I’ve been in this business! 
Let me just say it this way…….. You cannot purchase a gauge compliment mounted, wires and backlit better OR for less money…. period. His web site is www.custominstrumentpanels.com . Here is the dash we’re putting in right now. 
It’s kinda interesting but we are replacing one of Mac’s older dashes with the new…GPS driven speedo…… all new and fresh.
Stay tuned for more on this project.
So it’s still crazy around here trying to catch up after the hurricane and a weeks no output because of no power. Unfortunately it will effect deliveries. What can I say, there’s no “work harder”… we’re there already! Please bear with us as we dig out. OK…. I need to get out there… see ya tomorrow.
Love your work! Hoping to buy a GMC Motorhome soon – been thinking about it for a few years…will definitely see you to update the dash!!
