Welcome to RV.net!
Here is some reading from Roadmaster.
RoadmasterI would suggest talking with people directly. Some posters here live near you. It may help to go by one of the parks near you and talk standing along side of a tow bar rig setup.
Don't take the talk from dealers as to what you need. Be careful of Poulsbo RV! Some will sell you more then what you need or push you into something you don't want.
Check with sites like Roadmaster for tow bar brackets and different types of tow bars. Some are easier to hook up. I like our Stowmaster because there is only one connection to hook up. Arms that extend saves some because you do not have to position the car exactly.
You small vehicle you may want to have a MH mounted tow bar. slightly less weight on the front suspension.
Lights can get to become an issue. For several years we used a set of magnetic lights with the wire draped along the roof. I later added wiring under the car and still used the magnetic lights. Good price for them at Harbor Freight.
