Yeah, DD, on the EX. I can find ways to get 30+ mpg on certain legs of single trips, long enough to fill up and proclaim victory.

Big congrats on the new numbers!!!

Have you looked at heaters for all fluids? Engine oil, coolant, axle and transmission?

Spent a short time in CL-8 Sterling daycab with temp gauges for the above. Same route, same conditions. Took over 40-miles for heavier fluids to come to 175F (pulling a fairly heavy 57' trailer) on level ground, 90F ambient at 65-mph.
