I did the Alpine Loop this summer, my 3rd time to do the loop, in my RZR 4 and went all the way around on it (70 miles) on 1 tank but that was its max. With that said I just did 105 miles in my P1K5 and it took about 5.5 gallons to fill it up so I have no doubt you can do the loop in a tank of gas in the P1K5 and still have some left. FYI, I also carry an extra 5 gallon Jerry Can of fuel when I ride the loop for that just in case scenario. Its better to be safe than sorry.
