To the 6.2's credit, it handles it fine up the mountains in the Smokies. It is still very stable. I've always heard 3/4 tons are derated to hit the 10,000lb mark; maybe that's why. I do have the stiffest springs available due to the way it was optioned and added Timbrens.
I pulled my 2018 30.5 MBOK home from the dealer using a 2007 GMC Sierra 2500HD with the 6.0L gasser. Now, the 3/4 ton was able to handle the load just fine because it was the HD, but the truck had to really work at pulling it up the hills. If you hit even a slight a head wind, it would really struggle.
Engine and transmission temps ran high the whole way home. Good thing it was only 250 miles!
2 days after buying my MBOK I upgraded to a 2013 GMC Sierra 3500HD with the 6.2L Duramax and single rear wheels. It pulls the MBOK around like it's a popup!
Simply put, I would NOT recommend a 1/2 Ton p/u for the 30.5 MBOK. Even unloaded, your not going to be happy with it.
