That 1,000 pound restriction sounds good 20 years ago with the much lighter trailers but becomes an issue with the current 28' models with a factory 2016 literature tongue weight of 976 pounds before any hitch is attached or propane is put into the tanks. Since the factory numbers are low to begin with, that model trailer tongue would always be overloaded.
