Safety chain weight capacity

[badrano]

I need to replace the safety chains but the vin plate on the trailer is unreadable to determine GVW. From the paperwork, I have the vin and ran it through a vin decoder and based on that, the model number indicates a 4200 lb carrying capacity. Should the 5000 lb rated chain be adequate since there will be a pair of chains?

Yes, 5000 will be fine.

Thanks.

Another capacity question...what should the rating be for the transom tie down straps. The boat is 3400 lbs dry.

Think of it this way, you are securing the trailer, to the boat.

Here in Australia it would be about minimum working rating of 200 Lbs per strap (2).
Note, that's working rating not a breaking rating which by memory is about 3 times higher.
They don't need to be tightened to that, snug is fine.

Check your own regs to be sure.
