Ran it over to the lake again last weekend:
We opted for one last hurrah before I put the Skamper away for the year.
Got her packed up again...
One thing about this thing, especially when in the top bunk, the view out the back can be really nice since you are up so high and it has windows all around the sides and rear
It was a pretty light crowd which was strange because the weather was really nice...
Truck was running heavy and un-aerodynamic obviously. Water tank was dry but the camper was full of gear with a bike rack and three bikes hanging off the back. So naturally wanting to test my work I flips the A/C on.
It was a 10 mile run, it barely got up to 203* once but for the most part settled into the mid 190*s. I think it was saying like 198* when we got there. It has a OE rated Explorer thermostat, I think around 195*.
This kind of confirms a theory I have had. Before the fan relay block was fully functioning the fans would kick on when the engine got warm enough. All the A/C could do was dump heat in front of the rad in an effort to get the engine to warm up quicker to spur he fans to work. By then the temp was climbing fast and just continued to climb as the fans fought to pull it back down.
No doubt it did no favors for A/C function either...
Now, when I flip the A/C on the fans come on too and they cycle on/off with the A/C compressor. So with the fans running the engine seems to heat up much slower and then the cooling system doesn't have to try to get ahead of it and cool it back down.
So that is pretty neat if it isn't a fluke. I drove into the park to the campground at 20mph or whatever and the fans were still cycling with the A/C which meant the ECM wasn't calling for the fans to run due to engine heat.
