car trailer advice
I use a 1978 Simmons trailer. Surge brakes on both axles, open in the center (20 foot runways for the tires only), with the fenders retained by a slip fit bracket at the front and a hairpin at the rear. I love it. Since it has no "deck", just runways, it is very light. Being able to pull a pin and pop the fender off on either side makes getting the doors open on low vehicles painless, and makes trailer service / brake jobs much more pleasant. Kinda have a love / hate thing with the surge brakes, love not needing to put a brake controller on everything I might ever tow with, hate the whiplash you get on PAs tar stripped I-80.
Oh, by the way, PA requires brakes on all axles.
