Hello everyone,
It appears that most 2 horse BP bumper trailers are manufactured with a 2 5/16 in coupler assembley.
Does anyone know why a trailer would be manufactured with a 2in coupler?
I don't KNOW why, but I think the 2 inch ball was common maybe 20 years ago, perhaps even more recently. I think the 2 5/16 was introduced for a weight class, e.g. over 5,000 lbs. 2 inch is still common on small boat trailers, 1 7/8 on small snowmobile and jet-ski trailers. If you go back far enough trailers were smaller/lighter and so were horses, so it is POSSIBLE that the ball/coupler sizes and their specs were always there - we just started to haul bigger horses around in bigger trailers as bigger tow vehicles came into vogue... ahh, maybe not (-:

Older trailers I've owned built in the 80's had 2" hitches. Even a 20' stock trailer we owned. Now it seems it is just supersized -- though many 2" and 2 5/15" balls have the same sized bolt. Wouldn't that be the weakest link? Is anyone old enough to remember when you bought a cup of Coke it came in a little 6-8 ounce cup instead of a 64 oz jumbo size?
