Wow, what a difference from a 03 Sierra 4.8l regular cab short bed. No more porpoising or being pushed around by passing big rigs. Plenty of power with the 6.2l. The drive is much more relaxing now and can go further without being exhausted. [emoji4] Got 10.3 mpg going to Navajo Lake with a long gradual climb up the continental divide.
Attached are my CAT numbers before we left. GCVWR is 15k, AWR are 3950 each. Will weigh just truck when we get back.
Safe and happy travels.
