Not that we will, but we can! When you are taking your camper to your daughter's college graduation tomorrow and you find out the water heater is rusted out today, and no one has one on hand, we do what has to be done! Any bets on how long this repair will last?

At Lair Diesel Repair we aren't just working on engines and transmissions. This truck we're working on got the full HVAC treatment. Axil pulled the dash for me, I rebuilt the heater box with new aluminum blend doors (instead of the plastic ones that break, new heater core and AC evaporator core, and removed whatever creature nests were in there, and refoamed the seals. While we were at it we replaced the cracked dash top with a new abs plastic one from Genos Garage! We are also putting an android stereo with gps and a backup camera, along with some kicker speakers all the way around. You just never know what I won't say no to.

By the way, That's "Camera shy Casey" from O'Smiley auto parts in Estherville. If you know him tease him about it. He generally takes it pretty well!

We work on gassers too! This 6.2 Ford came in with a hard miss. Axil quickly located a broken valve spring using his scope and performed a relative compression test. Expert diagnosis means the repair costs less because less time is spent figuring out what is wrong.

As it turns out Axil has so many cool safety spectacles. He's really into safety!
