Gas pump keeps clicking off and slowly fills gas tank

I,like you sometimes have a problem with filling my tank on my Class C. Everything checks out OK but I have found that if I hold the nozzle at a 45 degree toward the rear of the Motorhome I have no problems.

I also have the same problem on my GMC Yukon the trick also works on it too.

I have also found that some stations it can be a problem,Example,the older Sams Club here I have a problem but at our New Costco not so much.
