I abhor truck stops and have no problem pulling my truck and 5th wheel into service stations. In 6 years of fulltiming I've only had to back out twice once because someone blocked me and the other was in the first 4 months of towing. You just have to scope the station quickly and pass it by if it doesn't have good access and egress and make sure the canopy is high enough.
Better practice that backing up, I learned real quick when I went down a dead road, again during the first few months of fulltime travels.
