Glass 1/2 to 3/4 full??

Thursday's plan was to go to a local campground, de-winterize the RV so we would have water and toilets.  Also we just wanted to stay in it for a night as a test.  We hooked up the Jeep to the back of the RV.  We are now 56 feet long! Once at the campground we began our process.  Back in to the site, hook up 50 amp electrical, hook up water, hook up water drain line.  We drained all the antifreeze and turned on the water.  Excellent.  We have electricity but the refrigerator does not seem to be cooling.  Microwave works.  Toilets do not flush properly so we refer o the manual to see what we did wrong.  It says there is a switch we need to turn on that will activate the vacuum system for the toilets.  Great, where is that??  Found it behind some towels we had hung turned it on and the vac system activates.  Great.  Bleed and fill the hot water tank and turn on the electric heat for that. Great. Now we notice that there is no display on the thermostat therefore we have limited heat in the unit and no heat to keep pipes from freezing.  It is supposed to get down to just below freezing to night.  This is a problem.  We have have this problem before so I change the fuse in the thermostat...pop!  I changed it again...Pop.  Called the RV dealer and spoke with one of the technicians.  Bottom line is to bring the unit in.  Well crap!  So we disconnect everything, drain as much water as we can and pull out of the camp ground.  But since we had paid for the night they said we would have one night free next time we are there.  We get to the RV dealer and they need the unit for several days.  Hopefully we get it back late Monday.
So we got some good things done, but not everything we were hoping for.  Plus we did not get to spend our first night in it.  I'll rate the day as a solid B.
