any good advice about towing a car

Completely agree with the suggestion for practice. The only way to get used to towing is to tow! Your car should follow directly behind your RV, so turns should be fine. I'm guessing you take your turns with your rv a little wider than with a car anyway. Always understand that you are now much longer than before. Don't ever assume someone will move over for you or give you room just because you need them to. Always signal your intentions and remember to be able to see any vehicle you pass well behind where you think they need to be before you go back into a right hand or left hand lane. Just be patient, let other drivers know where you need to go, and you'll be fine. We tow '4 down" (don't use a dolly) so we cannot back up when toad is attached. Wouldn't advise it even with a dolly. When pulling into a parking lot or gas station, be certain you have a direct path out because turning around in a limited space can be torture - if not down right impossible. We almost always use truck stops (Pilot, Flying J, Loves, etc) when we have our toad. They are built for RV's and maneuvering around is not a problem. You acceleration time will be greatly increased when you tow - you can't just 'hit it' and expect to move faster right away. Practice is the only real way you can get the right 'feel' for how your rig will handle/react with a toad. Enjoy, and be safe.
