No problem, I did not take your comment as derogatory at all, I just wanted to ensure I was understanding correctly, hence my qualification statement. Sorry if my response was perceived as being critical. Not intended at all.
I think as one reads all the posts on this subject, the general preference for gen fuel is diesel if that option is practical. For example, I would not expect to see a diesel gen in a gas coach.
I would not buy a coach with a propane gen because of the limited sized tanks and propane is not as readily available as diesel or gasoline. I want my limited supply of propane for cooking, refrigeration, HW and coach heating as required. But others might be quite happy with a propane gen. If one does not hardly use the gen, well does it really matter?
And indeed diesel engines need more heat to start than propane or even gas engines in cold temps.
In weather that we are normally using our RVs I had no problem with the usual glow plug warmup, but as temps get colder, well additional heat sources are required. I had pre warmup heaters installed in my diesel engines. The diesel gen for my S&B backup was 18kva (about 15kw with a PF of. 8) I had a thermostatically controlled block heater. Since it was on "autostart", I wanted it to go when I was not there anytime the main power failed. One time it totally failed when I was away and the cause was contaminated fuel. I changed to a propane gen for fuel management reasons only. The diesel in my opinion was better gen with better performance but all that is useless if the fuel goes bad and it will not start. (This is not normally an issue with RVs because the fuel supply is replentished quite often and fuel supplements are used.)
Hope my post provides usefull info. I always intend on being helpfull.
