I found a trailer local and the price is right, so I'm thinking about buying it. Mine's getting pretty rusted. Anyhow - my question is this: Are all bunk configurations the same or am I going to have to really watch? The trailer I'm looking at is a 2001 and all the guy knows is a "20' boat came off it" - it IS a Triton trailer, so I'm thinking maybe a TR-20 was on it?? I've got a 2004 Triton TR-196. Thanks
