BTW Redland did you get your A/C fixed?

On my A/C I’m still running the compressor with a switch until this oilfield job wraps up and I can dig into it and figure out what the heck went wrong.

As far as the DD my bro is leaning towards a demandate even though I told him that there aren’t any good DD tuners out there.But he rather the truck not have a derate so he can service his customers 7 days a week than chase emissions issues.I was hoping he would go the route of maintaining instead of a demandate,but I get his truck is used strictly for oilfield work and doesn’t rack up miles but instead hours while the hydrovac side of the truck is working at 1500 RPM and the truck is stationary.
