what are people seeing for Max highway range in miles after topping up the fuel tank until it almost spills out of the ground?
For you with additional info for others as well:
If I drive normal like some other people do (which is abnormal for me), as in "no hurry", I can get 25+mpg on the highways, but only about 20-21 in constant, short drives around the city. I am retired, so no daily drives to work or elsewhere. Just sporadic drives to stores, appointments, friends/family etc.
Last month, we went up to Pinetop AZ from Mesa (Phoenix) AZ, 160 miles/3 hours one way, and going from 1500ft to 6800ft - AND BACK, with probably at least an additional 5-7000ft of elevation changes if not more. When we got back home, my average fuel was 26.6 mpg, BUT I was babying it and coasting to see what's the best it could do in up-and-down elevation driving. I would probably would have gotten only 22-23 maybe if I just drove like normal people.
HOWEVER, that is also with my wife at 150lbs, me at 230lbs, 100lbs of tools/emergency stuff in the bed trunk and at least 400lbs in the bed for a total payload of 880lbs. I don't count the weigh of the toneau since it is allegedly offset by no bed tail wind drag .
I also got 26mpg during a camping trip up to the mountains with my son 5 months ago with probably at least 100-200lbs more payload, but babying it that time too. Keep in mind though, coasting downhills rarely offsets the extra gas going up since you end up hitting your brakes to slow a lot. That makes me think a straight level road would do even better. I would guess 25mpg at 75mph on the highway driving normal.
TOPPING OFF: I almost always top it off when filling and more to the max when driving distances or having fuel points to use. I have filled my tank to exactly 21.0 gallons with a high probability of at least 0.5 gallons still in the tank which is not good for the pump, and also to 23.861 gallons when I stupidly was not paying attention. I still had no idea how I got to almost 24 gallons and so filed a complaint with the dept of weights and measures. However, I recently learned that when you go beyond filling the neck (3/4-1ga), some of it can return into the pumps vapor recovery system giving them some free gas at our expense and, much worse, it can possibly spill over into the EVAP system via the vapor intake hole, which can then be sucked into the charcoal canister which can only deal with fumes and can ruin it to the tune of a few hundred dollars or much more, especially trying to diagnose it. I have no clue myself. I now assume that because I was filling it so very, very slowly in order to totally max it (had $0.80 off per gallon points) that it was going back into the vapor recovery system, or perhaps somewhere else(?), and wasting much of my discount and time.
NOISE: Both my wife and I believe the cabin noise at highway speeds is better than average. But that is a very general comparison to other cars we ride in and our previous vehicles which were, we believe, average. We are both close to 60, so that is a lot of experience, but not something particularly accurate as most of our vehicles have been average to slightly above average in price.
TOWING: Twice I got 13mpg towing 2400lbs with about 500lbs on the truck to the California Dunes and back from Mesa AZ. Couldn't drive over 55-65mph the first time because the transmission kept overheating and the average temp was about 68. In fact, it overheated when I drove up to Flagstaff in November with only about a 900lb payload, going up and down hills trying to keep it up to 65-70. After getting the 30k transmission service at just over 30k miles, the second time we went to the dunes with the same load, no problem. I have no idea what the deal was and the dealer alleged not to know either.
Of course they pretended not to know why my hood fluttered dramatically too.
