what ever heater you use that burns anything needs to have all combustion products dumped to the out-of-doors.
PERIOD
"vent-free" heaters in a small space is just inviting disaster.
The government regulators must have been paid good money to allow the general public to buy and think the heater fumes do not need to be dumped out-of-doors.

I hope your new propane heaters are direct vent types.

But if you insist on spewing burnt fuel emissions (includes water vapor) into the small space of a bus, open the damn windows and if it is too damp out you will have to run a dehumidifier.

You can insulate until you have no more room inside the bus to crawl around, but the water vapor is still going to be present without ventilation and/or dehumidification.

Just use more heat and vent good. Gets you plenty of fresh air. On my old skoolie even running a coffee maker would fog the windows even with plenty of air leaks.Carpet on the ceiling and floor and factory insulation.

case and point for VENTED..

a couple years ago I installed Vent-Free gas logs in my home fireplace.. the logs I chose were designed specifically for my Pre-Fab wood-burning fireplace.. same manufacturer even..

the great room is a nice big wide-open area that leads into the kitchen and foyer.. tall ceilings, etc.. my house is 13 years old and has top of the line insulation and great wood windows..

I would often just turn the logs on all day and the furnace blower would ramp up on low speed just to circulate the heat through the zones..no heat required.. my logs came equipped with CO and O2 detectors.. after a couple of winters of really feeling RANK.. i finally figured out it was those Logs making me Sick, lethargic, and tired.. even though they never tripped any alarms..

this past late fall i took those gas logs out, and put the wood grate back in the fireplace... No more issues.. I was just in ohio for close to a month except for a couple trips.. being used to florida i burned the fireplace nearly every day all day..

so even though your CO detector may not scream doesnt mean you arent getting hurt by it..

If you are going to heat with un-vented propane then you are going to have moisture issues.....

I run two small electric heaters, a 60 pint dehumidifier and I wear a sweater. My condensation issues are manageable but just barely.

I do use propane for cooking and that adds enough moisture that I cannot imagine heating with non-vented.
