Understanding Inverter on Sprinter

GVWR (Gross Vehicle Weight Rating) is your van's maximum allowable weight including passengers, cargo, and fluids. Exceeding this is illegal, dangerous, and voids insurance. Payload = GVWR - curb weight. Most cargo vans have 3,000-4,000 lbs payload capacity. Track EVERY item - a full water tank alone adds 250+ lbs. Use a spreadsheet to calculate your running total before installing heavy components.
