Help!

I'm struggling to find the tongue and gross weight for a 1973 Terry
travel trailer. Trailer body measures 20 feet long.

The trailer has the spec label in place, but it has been sun-bleached
and is unreadable. I've tried the vendor and all the major parts
suppliers--no cigar.

I can always take it to a public scale--but this won't work for the
tongue weight.

Thanks in advance!
