It's one of those things one worries about quite a bit when new to towing, but doesn't matter much after some time behind the wheel. After five + years and plenty of guidance from kind folks here, I don't give it too much thought anymore. True, it's nice to be surprised with easy in, easy out, but I don't obsess over it like I used to. If you can pull in, you can back out. Just a matter of convenience. Take your time, don't let anyone hurry you, and stop worrying so much. Most folks love to help "rig" drivers negotiate obstacles. Just don't put too much faith in strangers judgement. Never be afraid to look for yourself. Swing wider near the pumps, keep the arc going after you pass, don't straighten it out too soon. Use a spotter if you have one. Beware of thoughtless people in a hurry. Lots going on at gas stops. Don't forget to do a walk around of your rig at every stop. Be safe!
