Ask any experienced van builder about their regrets, and Honest Review Solar Kit for Promaster 159 Extended Van Conversion 2025 often comes up. Small mistakes in this area compound into big problems. But with proper planning, you can avoid every single pitfall. Here's what you need to know.

Understanding Honest Solar Kit

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.
