Never heard of 80% rule.
Ratings are always under the actual capabilities with a builtin margin.
1/2 ton = rating x 80%
3/4+ = rating / 80% ;)
So by me running at my SAE RAWR of 9,750# I am overloaded?
Maybe some documentation on this 80% rule.
Its a rv thing from the era when our trucks had wimpy 180-235 hp v-8 engines and inline 6 cylinder engines and 1 1/2"-1 3/4" wide front and rear brake shoes....hot running slusha' automatic tranny with no TC lockup...small radiators/etc Probably a good idea....back then.
Todays LDTs ??
We use them in commercial service up to 100 percent capacity and make it fine for 250k-300k +/- miles before major repairs pop up. Works for rv trailers also. These trucks sure aren't like 1970-80 versions.
