DMV title and registration
In the US, there is no mandatory government inspection for DIY van conversions like in European countries. However, you will likely need to reclassify your vehicle title from a commercial van to an RV (motorhome) at your state DMV.
1Requirements vary by state. Some states (like California) have specific criteria for what qualifies as an RV: sleeping, cooking and water facilities.
2Visit your state DMV to apply for a title reclassification. Bring photos and documentation of your conversion.
3Your vehicle must still meet DOT (Department of Transportation) safety standards for roadworthiness: lights, brakes, tires, emissions.
4Some states require a safety inspection or emissions test, but this is a general vehicle check, not a conversion-specific inspection.
5Title reclassification fees are typically $15 to $75 depending on the state.
Taxes and registration costs
The US does not have an equivalent of the European BPM vehicle tax. However, converting a commercial van to an RV can have financial benefits for registration and insurance.
1Reclassifying your van as an RV can lower annual registration fees in many states.
2RV insurance is often cheaper than commercial vehicle insurance, and may include full-timer coverage if you live in your van.
3Sales tax applies when you purchase the vehicle. Parts and materials for the conversion may also be subject to sales tax.
4Some states offer reduced registration rates for RVs compared to commercial vehicles.
5Check with your state DMV and insurance provider for exact costs. Rules vary significantly between states.
A gas installation in a motorhome must meet strict safety standards.
1The installation must comply with NFPA 1192 (Standard on Recreational Vehicles) which covers propane and gas systems in RVs.
2Gas bottles must be stored in a ventilated compartment with drainage to the outside.
3A pressure regulator and gas hose must be inspected and not expired.
4Mandatory: a gas detector or leak detection system.
5Have a certified RV technician inspect your gas installation before use.
Electrical installation
There is no formal inspection for 12V/24V installations in most US states, but safety standards still apply.
1Use cables of the correct thickness (see our Cable Calculator).
2Fuse on every circuit, as close to the battery as possible.
3Lithium batteries must have a Battery Management System (BMS).
4AC installations (shore power/inverter) must comply with the NEC (National Electrical Code). Consider having a licensed professional inspect your AC wiring.
5Keep cables away from heat sources and sharp edges.
