Your SF20 is a Suburban 20,000btu furnace
It should be able to warm up/maintain a small trailer
Only warm exhaust means burner is NOT functioning properly.
Dirty, clogged/blocked burner slots, low propane pressure etc resulting in a very low yellow flame vs a STRONG BLUE (HOT) Flame
Here is an Installation/Operating Manual
