Is a GMC truck just a dressed up Chevy truck?

If it wasn't for the ex forcing sale I'd still have Black/Grey GMC 1 Ton 4x4, 454, 4.11's. 11 MPG uphill or down. Era of the 454SS. That truck rocked !
'89, SnugTop w/ carpet kit, cooler, custom campbox w/Coleman stove, pans,cooking yit, spices etc. 5 Gallon LPG fit under the bed. Rack in the receiver for xtras if not towing the CJ.

Trips to Idaho, Eastern Sierras. I'll never forget She B. Gimpy the pit flying thru the slider breaking the windshield/rearview off PO'd at passing dog in the fast lane NB 101 at the start of a trip. The ex was throttling her as she wasn't happy after jumping over the 7 month old in the infant seat. Whoops !
