Sounds like your going to be having some great times. You will be able to fit in 99% of all gas stations right next to the major highways. The "driving in" is not the problem you need to make sure you have overhead clearance. What ever you do never forget your about 12 and a half feet high... Just keep that in your head when pulling your rig. You might even want to paste it on the steering wheel. We have a lot of dog shows down here for sure. You should have a blast. Don't worry about fuel there is always a place that will be more than happy to take your money.
