I wouldn't be disappointed with that. It is rated to give 33 Hwy, you got 31.5. Sounds fair to me. Speeds, hills, temperature, wind and many other conditions factor into it. Hybrids really only shine in the city/around town mileage. On the highway road trips the engine should be running almost the whole time.
Yep, don't believe the dash MPG. It's clearly a very liberal estimate and almost always 1 or 2 high. However, I'm routinely beating EPA at 43-45 MPG calculated manually. Got 47 once, but that was an outlier and I'm not exactly buying it. City driving of course. Looking forward to finding out for myself what she'll do on the highway.
I agree, however, many people think it is, not worth the bandwidth to convenience them.
Following a recommendation from the owners manual:
It has gotten real hot here in Kansas City the last few weeks and the A/C is really working OT. My mileage was down a bit. After a couple of highway runs recently have got most of it back. A couple of short trips where the vehicle was very warm inside were the culprits. 85% of the time I am parked in a garage with HVAC. Last weekend I registered 39.5 mpg on two 35 mile trips of which 25 miles was interstate each way. I am going to throw the 3A max charger with float mode on my 12v battery overnight that is under the rear seat . Can't hurt.

I trust your charger has an AGM setting? You can attach the charger to the + jump post and - frame post under the hood. That's what I have done. My CTEK has an AGM reconditioning mode and I did that before my trip......just because. It took the charger about eight hours to complete the reconditioning mode. All is good.

I am going to find a pp monitor with more stringent specs my current one is supposedly accurate to +/-0.1volts. on mine I see immediate jump to 14.7. since the pp reading is on an open circuit there could be a slight variance your 14.5 and my 14.7 could be closer together than 0.2 volts. In any case the recommended saturation charge voltage for deep cycle 12v batteries is 14.6-14.8. the amperage will be adjusted to power everything plus what's needed to charge battery. Depending on battery your 14.2 indicates your 12v is well over 80% charged.
On agm batteries leave on float mode until it goes into maintenance mode. Need to insure as close to 100% charge as possible. In winter it's best to store it in non freezing location and put agm charger on it for 3-4 days every 4-6 weeks. Or maintenance mode all time. I just rotate charger across all my batteries from time to time.
How hot was it. Was it better one direction than the other. With my Prius I've seen a difference between 50+ MPG and 35 MPG depending on wind. Also if it was very hot it affect the performance of the battery.
It was over 100. Mpg was both way similary low but on the way back I had some loads in the bed. I have somehow the feeling that after I passed 10k my mpg improved and I am almost back to normal, where I started with my truck.
