Best Pin Box?

I'll kick this one off. I have a Reese 5th Airborne 20K for our 2013 Arctic Fox 27-5L. As long as it will hold air it's performed well for us. No chucking, bouncing . I also have the B&W Companion hitch which helps also. I will have to admit we don't put as many miles on it as a lot of folks here might, maybe 2000 a year. Good Luck
Bill
