Cirrus 820 mounted on GMC
I have a 12 foot garage door. Will the camper on the truck fit? The GMC is a 2500 HD duramax with helper springs and standard wheel rims. The 820 will have a roof top AC

Cirrus site says the 820 height is 9’8”. I think you are going to be very close. I’d also make sure the 12 door is really 12 from bottom of the door open to floor. If it is just a little off on adjustment, you could lose a few inches.
