US tour - southern states, 2013

We don't keep the freezer divider in place, but the temperature sensor was on the top shelf.  With the temperature control set to 5 it got down to 29 degrees the next morning, then I changed it to 1 and it went up to 45 when I got home from work.  Set to 3 it held in the upper 30's.  All of this time the outside temps were in the 60's and 70's.

While on our trip AC mode would hold around 39 degrees with outside temps in the 80's and 90's.  DC mode was a bit warmer in camp and would rise up to 70 degrees on the road.

I believe I've solved the fridge problem when in gas mode.  Today I pulled the burner assembly out (still attached, just loose) and blew a strong blast of air on it. The flame was then much stronger. Where it wouldn't cool at all during the trip, right now after about 4 hours in gas mode it is now reading 34.5 F.  Yay! 

I also opened the chimney and pulled out the diffuser, then blew air down there, but it was all clean so I'm sure that wasn't the problem.  The diffuser didn't have any carbon or dirt on it.

I can only guess the struggle was due to very high grades - I think the 2 spots I had a problem with were over 10% - and I have been running the tranny rather warm due to the generator box up front (a problem I'm going to fix before I use the box again).  

We did tour Green Bank, my wife hasn't caught up on the blog posts due to being in the "national radio-free zone" around it.

Back home safe around 5 today, time to get to bed!

Originally posted by techntrek  It was also struggling at the two worst parts, I hope not a symptom of a problem.  I don't expect any struggles with over 300 hp and torque and a trailer less than 3000 pounds...

That surprises me.  We had a Yukon and towed a 6800# travel trailer all throughout the Southwest, up and down 6-7% grades.  Other than having to shift to a lower gear every now and then, we had no problems.  I would not expect your Suburban to struggle either.  Back then, our towing average was always around 8.5 mpg.

When we went to the Eastern Rally in NC, I thought about kicking the monitor over to "instant mpg" going through the Cumberland Gap on the Wilderness Road.. I decided not to because I was afraid it would make me cry.
