As mentioned you have to retrain your fueling mantra. You have to look ahead and see if you can fit and more importantly can you get out BEFORE you pull in.
As far as really steep grades or tight turns you might be apprehensive about? If you are traveling with family etc. I have seen quite a few RV'ers unhook at the bottom and a family member drives the toad up and to your destination.
I've traveled with and without a toad and I now would not leave home with out one. Traveling with dogs and the few occasions I have broke down having the toad completely illuminates the 'crisis mode' an RV break down can put you in.
You break down, call a tow truck, unhook the toad load the dogs, toss the keys to the MH to the tow truck driver and tell them to call you when it's fixed....and drive off in your toad, I love it!! :B
