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.

Common Mistakes to Avoid
3. Focusing Only on Upfront Cost
The cheapest option often becomes the most expensive. We've seen too many builders replace budget components within months. Quality matters, especially for items that are difficult to access after the build.
5. Overlooking Maintenance Requirements
Even 'maintenance-free' systems need occasional checks. Battery terminals corrode, connections loosen, and software updates may be needed. Build maintenance access into your design from the start.
2. Ignoring Future Expansion
Your needs today might not be your needs next year. Many builders wish they'd bought a slightly larger system to accommodate future upgrades - like adding more appliances or extending their travel season into winter.
