I installed a Hidden Hitch on the front of our last pickup, a 2002 Dodge Cummins. Bought the spare tire carrier and bike rack for it. Both worked fine.
With my current Chevy, I can see that part of the plastic, on the front bumper will have to be cut away for the hitch to be accessible. That may be one of my next projects.
Sure do wish I had an auxiliary tank for my truck. I can see where it is a real personal matter, for those that just drive a short distance and camp for a week or two, probably don't need one. But for those of us that use our TCs for long distance travel, it would sure be handy. On our trips to western Colorado and to Alaska on alternating years, we normally fuel up twice a day, some days only once if I don't mind running the tank lower than I prefer to do. Especially on the Alaska trips, as the OP points out, it isn't just the availability of fuel but the price. With more fuel capacity, I could just fill up in the larger population centers and save some bucks.
Even with the TC, especially when we are towing our Jeep, getting into and out of, many stations can be a challenge. If I only towed our 5th wheel trailer, I would put a larger in bed tank, in permanently, but with the TC, that won't work so the larger underneath tank is about the only option, IMHO.
While there may be a small reduction in fuel mileage, when running heavier, once out on the prairie flat lands and up to speed, I doubt it is much of a loss. If it were a direct relationship, the rail trains couldn't haul the vast amount of freight they do, on very little fuel per ton of freight. From a standing start, I can see the loss would be more but once up to speed, on flat ground, don't think so. I ran a couple of recent round trips to Alaska, with the former Dodge I owned, but with two different TCs. One of the TCs was considerable heavier but the round trip fuel mileage was about the same, close to 15mpg. I suspect the speed driven and the frontal area of the TC and wind resistance to that, is more of a factor than the actual weight. I figure it costs me about 1/2 to 3/4 mile per gallon towing our Jeep Wrangler, behind the TC, which the Jeep Unlimited weighs close to 4,000 loaded and ready to go.
I found the front hitch very handy at times to launch my boat when I had the TC loaded. Put that boat up in front of you and you can thread a needle with it. Sure is easier when you can see what you are backing.
