Yes, will need an extension as well. Hmmm, brake assist never crossed my mind. Have one on our 10k lb. flat bed trailer. Thanks.Yes, hitch extender is needed for my camper. I already have a Roadmaster sterling towbar. Safety cables/chains. Wiring for lights on back of the jeep. I have flat towed 10's of thousands of miles with 3 different vehicles. Jeep will be the fourth. You should also probably have some type of a brake assist assembly in the towed vehicle. Will also stop it if it becomes disconnected. Lots of info on line about this. It was a game changer for my wife and I to have another vehicle to get around in. We will never be without it.
