Until I get it insulated, is it going to make any difference weather I heat it with a Mr Buddy propane heater or with a electric heater as to the amount of moisture it will get on the inside.

As was mentioned, propane produces H2O when it is burned.
I assume there is plywood on the interior, installed over the wall ribs. If it was really cold you might see some frost on the plywood. Possibly some liquid condensation. The plywood can also absorb some of the airborne moisture. If moisture laden air gets behind the plywood it would most certainly condense and maybe freeze if it was cold enough outside. You won't see that. If it was really cold and humid you may end up with liquid water between the inside and outside walls. You probably want to avoid producing any H2O inside with a fuel burning heater. It can be bad enough with a couple people simply breathing all night.
Speaking of breathing all night... I have a super sized dislike of non vented fuel burning heaters. The danger being the production of CO, Carbon Monoxide. Perhaps you are well aware of the dangers; perhaps not. So, in brief, our red blood cells prefer to pick up CO from the air we breath over picking up O2, oxygen. Any amount of CO is bad for us. The blood cells do not give up the CO once the CO has been absorbed. The blood cells hold onto that CO until they die. Lifespan of a RBC is about 100 to 120 days. Cells are dieing and being replaced all the time. So when we breath in a dose of CO some of the cells holding CO will be dieing off tomorrow while others will circulate around the bloodstream for a hundred or so days, without being able to contribute anything worthwhile, like carrying Oxygen. In a worst case scenario there can be so much CO tied to the RBC that even breathing pure oxygen can not save your life.
I got rid of all my unvented fuel burning heaters a long time ago.
We do use a Honda EU20001 at times to power an electric heater. Those times see the generator as far away and downwind from the trailer as I can get it with the two 50 foot cords I carry. Reason; gasoline engines can produce CO too. A CO detector / alarm is good but once it goes off you have already been breathing some CO. Probably not a lot unless you just walk into a room / space with a very high concentration present already.
