Karen,

That SPAL blower is rated at 667 CFM.

Let's roughly calculate the internal volume of a 26 foot GMC: 25 feet X 8 feet X 7 feet = 1400 cubic feet

Lets guesstimate that blower is 50% efficient due to pressure drop through the mod Tom created; 1400 cubic feet divided by 330 means
that blower could replace all the air in a GMC in 4.24 minutes.

Seems like overkill to me.

Unless my logic and calculations are incorrect, which is quite possible.

It looks like other brand blowers are easier to find.

Would this SPAL brand work? Or is it too many amps (not sure how to read their table):

I think the OEM blower has a 30amp fusible link.

How about this one by RedDot:
