Question 12V compressor on Monty batteries??

Thinking of getting a Vair 300. It has an 8 ft power cord and a 25 ft hose. I don't think it would reach from the truck to the tires. But it would reach from the house batteries. Will this drain too much juice from them? Or would I need to keep the truck running???
Anyone with experience or advice, let me know your thoughts.

Just as a safety precaution,I would leave the truck running while using the compressor. That way you know it WONT drain the coach batteries.

It draws 27 AMPs max. I would leave teh truck running. I do not think the truck will supply the 27 amps through the 7 pin connector. So even with the truck running teh batteries will go down a bit.
