This sounds like normal operation to me. What's the issue?

It means nothing, just letters. Just like Acura TL and TL and RL.
Unofficially people say "Comfortable Recreational Vehicle".

Yes, but not recommended. The towbar gives you better control and helps to reduce the chances of vehicular damage to both vehicles

Most cars are about 1/2 ton capacity(1000 pounds) Towing a small trailer should be fine as long as the weight at the hitch ball is less than 200 pounds. Load the trailer so the most of the weight is on the trailer not your car.Remember to keep the tire pressure correct on the trailer and your car and give yourself plenty of stopping space as the car will respond slower with the extra weight. Also try to take off kind of slow and easy so you dont over work your cars transmission. An add on type auxillery transmission cooler is recommended.
I hope this info helps you.
