I am seriously considering fitting one - in the SunTrekker we have 2 of the smallest propane bottles, in a barely legal/ safe locker. With a diesel heater I could use a small 5 litre Jerry can on a rack bolted to a rear panel. Less weight and we have gained a locker - that is wins numbers ONE and TWO. Win number THREE is out goes the Propex heater - yet more locker space or weight saving Win FOUR I think diesel use is cheaper than gas and diesel is far easier to source - last summer I took 2 days searching for small propane cylinders and used a lot of time and fuel. - a problem of living in Cornwall

The downside- there has to be one

So any experience will help.
