Red Blocker

I'm the happy owner of a 2015 2500HD 6.0 Flex Fuel Double Cab. When I fill the tank, I get in and turn the key, pause, then bump the key to start. It will turn the starter longer than needed (3 or 4 seconds) then let go. The motor usually fires, but once in a while she'll stall. Mind you, this only happens at the pump. I have not had this issue any other time. Thanks in advance for your thoughts and opinions!

I'm planning a 'Bucket List' road trip this summer, one place I want to go is up Pikes Peak. What is it, 14,500 feet? Sounds like I should bring some 93 octane with me to put in before I go up, are there other things I should do? I'm not in a race or anything, and I baby my truck since she's already at 230,000 miles. Thanks for any tips and tricks.

Since I already own my "Last Truck" as my wife puts it, Anyone know if the multi gate will fit my 2015 2500HD? I can figure out the electrical, just want to know if it will fit physically.
