I forgot to mention that I have a web page that shows what tongue strength is required to pass the Australian small trailer rules.
The maximum weight of a trailer with a 36" A-frame tongue according to these rules is:
2" x 2" x 1/8" angles: 380 pounds
2" x 2" x 3/16" angles: 560 pounds
2" x 2" x 1/4" angles: 710 pounds
2" x 2" x 1/8" square tubes: 1,240 pounds
These Aussie rules are very harsh and it would seem that it's safe to have a trailer weight of double these values.
Gerdo's twin 2" x 3" x 3/16" rectangular tubes are good to 4,300 pounds according to the Aussie rule, so they'd do for a 8,000 pound trailer!
