thanks for the info. I am in a similar situation. But I haul campers, cars, fifth wheels and I Hot shot for a living too and believe it or not after seeing all the issues this last winter about heaters and def freezing thousands of miles from home, it is my only recourse to delete this crap.
I am ready to get this done. Can you please pm me who you used to tune it? Are you happy with the service? Thanks much appreciated.
