We also are in CA and tow an 8000lb trailer around all the hills you mentioned. Our truck is a 2022 F350, 7.3l, 10spd, with a 4:30 differential. It is really a lot better than the 6.2l in our previous truck. In fact, we have no problem accelerating up those big hills even after getting slowed in traffic. Mileage around town is about 13 and towing on a level, no wind, freeway it's about 10.2. It really is as capable as one of our earlier diesels
Well 8,000# is not the same as 11,500# 5th wheel. To your point our 2001 Ram with a 5.9 CTD and 3.55 gears could accelerate uphill pulling a 13,000# 5er.
While the 7.3 Godzilla is a good engine part of the advantage is a 10 speed transmission and 4.30 gears.
