Glad to answer your question.
I don't know your experience level with your rig but if you have fueled it in and around the province the trip to Yuma will be no problem.
99.5% of fuel stattions along any Interstate hwy will be able to handle your rig. I have had 3 MH your size and traveled all over the USA and Most of Canada with only about a 1/2 dozen times where I thought the fuel station was to small for me.
Safe travels and enjoy the desert.
