on the OP questions, my biggest gripe on the 04.5 is the 26 gallon fuel tank. GM finally went to a 36 gallon on the short box in 2015. But if 26 gallons is small on a diesel, it's outrageously small on a gasser when your towing.
I installed a 52 gal Titan tank in place of the original 26 gal one.
I can tow 500 miles PLUS before I need to think about fuel. (I get between 12 and 13mpg towing)
Have run over 900 miles with no trailer.
It gives the opportunity to fuel at leisure, rather than when needed, plus the advantage of filling where the price is best.
Could I justify the $1000 on a payback basis - no way! But it sure makes life easier.
