RV Repair: Pop Up Heater, rv store, westlake

Question
We are looking at a 99 Coleman Westlake RV and the heater doesn't work. How much would it cost to repair (a broad range is fine) or to totally replace the heater? I have been searching online to find an answer, but all I can find is how to repair it, not the cost to have it repaired or replaced.

Thanks!

Answer
try online RV parts stores.  it think Tweetys.com is one.  you will find parts to repair, and also new ones.  to have the work done can range.  the rv store may charge $75 an hour or more.  If the heater is not working, it could be a simple igniter or plugged propane line.  may be an easy fix.
