If you're talking about the Shell at the intersection of US-6 and US-93, no problem. There's a large semi-parking area at the rear we used to turn around and get lined up to pull out onto the highway.
We went thru there in 2011 with our 31' class C towing (hooked up length = 31' + 24' = 55'). Not quite as long as what you're pulling perhaps, but we didn't have any issues at all.
I will usually wait for an outside pump or one that looks like it will have plenty of clearance. With the motorhome, I have no choice but to pull to the forward pump, but when we had a TT and 5W, we'd still pull forward to avoid being blocked in.
At the Sam's Club in Yuma, the staffer at the pump helped marshal me out of the spot, and even directed a few cars to other lines.
Just take your time, and as you'd do at a campsite with trees, use a spotter even if you don't think you really need to.
