Actually, no. The trailer part is simple, and it sounds like you have it figured out. You might shop around a bit for a better price, since you're getting close to the cost of the trailer added on to it, after you add brake controller, wiring, etc... The only reason we're cautioning your choice to pull the trailer with the car is experience. Since you're pretty well set on using the car, take it easy, don't try to break the speed record to get there, don't try to keep up with traffic on hills, etc...
