Fueling up older gas models

Our total length with our toad is about 55 feet, and we rarely have any significant problems refueling at most gas stations. As said, we do sometimes wait for an end pump island to clear. The key to minimal problems is to always plan your exit before you enter the station.

I bave a 96 Southwind, 37', gas. I've never had a problem getting fuel.
You learn how to check out a gas stop quickly to decide if you can get in/out easily.
I normally don't let the tank get below 1/2, then I'm not forced to get gas at the first place I find. I can check several places until I find something convenient.

In 90,000+ miles I have never had a problem fueling up. Mine is 50+ feet with the toad behind.
What I do is that once I get around 1/4 tank, I start looking for gas stations that i can fit in to. IN other words if i am driving on a road and see a station where I can get in to and out of easily, I stop. The biggest problem is waiting until you are almost empty and then you have to settle with what is close.
Fuel is used to cool the fuel pump that is located in the gas tank of many gas coaches. Running the tank close to empty too often can overheat and shorten the life of your in-tank fuel pump.
Another thing I do is at the end of the days driving, I always make sure that my tanks is close to full when I park for the night.
If you travel mostly on Interstates and stick with the stations along the highway, you will generally pay more for your fuel and that convenience. We travel a lot of the secondary roads to enjoy the scenery and we easily find small stations where we can fit. I have never had to disconnect my toad to get in to a gas station.
Since we do travel on mostly back roads is the main reason why I got rid of my diesel coach. At that time, not all small gas stations carried diesel but they all had gasoline. It was a good decision for the way we travel.

Most (not all) truck stops have pumps with enough space. Often you will have to wait for the pump you want, normally an outside island. Some truck stops have rv lanes with both diesel and gas. When traveling and looking seek out stations with pumps parallel to the road. Again, you may have to wait.

We always try to fuel up at the 1/2 full level. That takes away the pressure to find something fast. Start looking at stations as you pass by to get practice which type will work.

DW shares the driving with me and we both look and talk about stations as they come into view. Good practice if you travel with company. If not, just look on your own when you can, even when just driving a car for practice. Soon it will be no problem.

I have seldom had a problem.
Yes, my coach can (and does) take up all available lane room in some fuel stops by the time I get it positioned so that I have access to the fuel filler on the back.
I carefully watch where I am going, to ensure that I do not get into a position where I don't have room to leave.
Locally, the fuel stops I normally use for the car and pickup are adequate for the motorhome. When driving the freeways, I refuel at the RV lanes of truck stops.
I towed various Jeeps and a Dodge pickup four down, and a PT Cruiser on a dolly. No problems.
