Thanks for all the replies ,sorry I didn't get back to you sooner as we were on the road. We just came back to huntsville ont canada .Cold and snow ,had to wash off all the salt $#!% from the drive

Now a problem with heat yes heat ! on the drive from florida I couldnt get temp. over 140-150 f ? I had to jerry-rig my shutters to a switch on the dash and close and open manually to get the temp up to 180f . Outside temp. was as low as 19 f on fri. morning . And to top it off my electronic heat on the bus (red degital read out push botton ) so no heat out of defroster or main heater.( only worked 2 out of 10 times I tried ) , so the floor heat was not as hot as it should have bean and the propane wall heat helped to keep the front warm . Is there a manual heat unit for this bus ? IN the fall I replaced the thermostats for new 170 f ( org were only 2 years old when eng. was rebuilt) Now I installed new ones same as org. t stats could they be in backwards ? Or can they stick open ? since rebuild eng. has run cold . Frustrated as heck!
thanks dave
