Which heats a van faster?

The VEVOR, on paper. It is rated 8 kW against the LF Bros 5 kW, so it should warm the same space faster. The LF Bros has a lower minimum output, which suits milder weather better.

Is the LF Bros worth the extra money?

If certification matters to you, yes. The LF Bros carries ECE R122 and CE marks and a stainless combustor, and the VEVOR lists neither. For a casual garage setup, the VEVOR saves about $104.

Neither maker states a service life. The LF Bros' 301 stainless combustor is the more durable material choice on paper. The VEVOR's aluminum body is lighter but less specified.

Can I run either on 24V?

Only the VEVOR. It supports 12V and 24V DC. The LF Bros is 12V DC plus AC.

Which is better for an overland truck build?

The LF Bros. It is sold for overland and topper builds, is certified, and has a programmable timer. The VEVOR is the cheaper pick for a simple camper or cargo van.

How often will I refill the tank?

Less often with the VEVOR. Its 2.6 gal tank is about twice the LF Bros' 5 L. Actual burn rate depends on the heat setting.
