Another thread you said 6500 loaded ish?
Leaves less than a thousand pounds...
Too much. And it's not a fix. It's a bandaid. The rust will come back.
i was thinking about the GVWR or whatever it was;
trailer Dry is 4500 per mfg; I assume it has 500lbs if “stuff” between the tanks; water, and shit onboard, maybe more.
The Burbs cargo with dogs,gear, and 3 rows of people can be another ~1000-1500lbs, 6500 is every ounce of worst case In total.
