Hi: Garand... Dave; Never felt the need for one for this size of trailer!!! Looking at the weight ratio pin 480#s vs. axle 2160#s even when we're in bed I've never felt the earth move
Once I put our removeable step in the bike rack receiver( rear bumper) and stepped on it...YIKES!!! The trailer lifted off heading skyward!!!
I'm on a diet now... No sugar, no salt... BLECH :P !!! Alf
