I installed an electric fireplace in my 2955RL 2003 Montana.
After a lot of measuring and looking for the right size,
I purchased a Dimplex Model DF12309 includes remote on/off,
1440 watt heater/4800BTU for under $300

We just love the looks of the fireplace and the flame looks so real!
To view slides of fireplace - go to picturetrail below.
To answer the question about heat protection.
The heat comes from the front top of the unit.
Only the top front 1" ridge get hot to touch. No heat anywhere else.
There is 8-10" of air space from top of fireplace to above shelf
and the top board you see does not touch the top of the fireplace.
The fireplace can be taken out without touching anything.
We plan to use the fireplace year around - 5th & home.
