Built-in propane stoves usually come with minimum clearance information. As a guide, here is what mine gave as minimum:
Back of stove to back wall .....: 9"
Front of stove to end of counter.....: 1.5"
Left side to wall (if applicable).......: 2-5/8"
Right side to wall (if applicable).......: 3-3/8"
Minimum clearance from burner to overhead ceiling/cabinets (directly above the flame) is 19" for most all gas burning stoves.
Does it heat a camper up? Yes; but, the heat dissipates fairly quickly, especially if it's in an open area like a teardrop galley.
I plan to be equipped to cook either inside, on a built-in unit or outside, on a table with a portable unit.
I'd be more worried about distinctive smells than heat. So, keep it simple and quick and the smells should be minimal.*
