Really? Curious. I wonder why. Do you mind comparing specs? If so, how much does your truck weigh? Frontal area? Type of tires? Are you running synthetic lube in your tranny?
I run a 19 mile commute (slight uphill almost the entire way to work). I've had a battery die recently so I'm only running 14 T-875s right now (112V pack) and (according to the e-meter) it takes between 50 and 60% DOD for the commute. Back when the batteries were newer and I had all 120V it typically took less than 50% usually close to 40%. My longest trip, back then, was 32 miles with the emeter reporting 18% remaining. Though to be honest I couldn't go much over 30-40 mph uphill (slight) without going below terminal voltage though it could still maintain 45-50 on the flats. My truck weighs approx 3200lbs, it has Bridgestone Pontenza RE-92 tires (LRR I think) and Royal Purple transmission fluid in both the tranny and the diff. Even for a small truck, my pickup is small. It's about 63" wide at the widest and 64" tall at the talest with at least 7" ground clearance. By my reconing that means it's less than 25.5 sq ft frontal area. Oh yeah, I have a GE motor and IGBT controller, which means a good motor but (theoretically) a less than optimally efficient controller. Though to give the controller it's due, it has a large aluminum plate for a heat sink and even in 90+ degree weather the plate does not get hot to the touch. Then again, the most I can get out of my batteries is about 300 amps --and that's only early on when they are near full charge. Towards the end of my commute I'm down to less than 200 amps. Joseph H.
