I have one of the cheap $200 diesel heaters and it performs great, but if things were to go wrong with it, I can't see how it could lead to the camper filling with noxious gases, unlike a gas heater , I'd be concerned about sleeping with a device that produces carbon monoxide, although it shouldn't be able to get inside your camper.
Edit - spelling and extra clarification.
If you're talking about the direct selling Chinese eBay/Alibaba/wish diesel heaters.... I like your confidence...
Gasmate is an Australian owned business and therefore has to comply with Australian codes and have all the insurances along with it if something should go wrong.
We also have to have those insurances.
Not that insurances do much good for you if you're dead.....
However to get those insurances Gasmate had to have this product approved by Australian Gas Authority and comply with their Safety Regulations... Like most Australian regulations they are some of the toughest in the world...
The cheap diesel heaters I've seen are sold direct from China. Not tested or regulated...
If something was to go wrong... Very little if any protection.
That issue aside.
They both work the same way - they use heat exchangers that sit outside the tent. The carbon monoxide is expelled away from the fresh, warmed air inlet...
The only difference other than safety regulations is that one burns Diesel the other LPG.
