As mentioned earlier in this tread; a big part of the equation is the lack of insulation in the average RV. The average home has at R values of at least 6 in walls and 13 in the ceiling and HVAC ducts are insulated. Most RVs have little if any insulation in walls and ceiling and none on the undersized duct work.
Modern sticks and bricks homes built after the 1930s will most likely have 2x4 walls with fiberglass insulation with at a min of R11, in the 1990s or so fiberglass insulation manufacturers came out with an improved R value of R13 for 2x4 construction..
Modern day homes ceiling and roofing R value should be at R38 or higher.
Compare that to a RV with 1x2 wall framing the insulation in the walls will be R2 or a bit less and if you are lucky R6 in the middle of your roof and R2 at the ends of the roof.. Then consider that your RV floor will have at best R2 in insulation..
Sticks and bricks homes are built with double pane glass windows, typical RVs use single pane for a zero insulation value..
You can basically call a RV nothing more than a cardboard box and you are trying to heat not only the contents of the box but the air surrounding your RV.
It is what it is, if you are planning to camp in cold weather, plan to use a lot of propane.
