8.1L Suburban Opinions?

Picked the new trailer up today. 31' enclosed.

Mixed 75 / 65 mph driving, I averaged 7.8 mpg with it .... in other words, exactly what I expected.

If I downsize my tires back to the 265's or even 245's t hat number would go up.

I think I'll take the happy medium and put the 265's back on it.

Also, I was towing this @ 75 mph on the flats and slight inclines 5th gear today ....

big blocks pull pretty good ;)
 
GMC/Chev needs to bring back that motor.

Two things they need actually:

1) bring back the 8.1 gasser and put it in subs and yukon xl's...
2) put the duramax in subs and xl's...


chits easy....what other problems you got to solve today?
