Been a while since an update but making good progress. I've got a few trips under my belt now and getting a better feel for things.
I found myself to be using the roof box a lot which means a ton of trips up and down the Aluminess ladder. Unfortunately the ladder was supplied without any sort of grip tape or knurling on the rungs and was a bit deathy when wet. I hit my local skateboard shop for some grip tape and it's all good now -
I went up to race the Idaho 100 ISDE enduro a couple weeks ago which was my longest trip in the heat with the National Luna running off the factory aux 100ah LA battery. The Luna seems to really sip the power, especially considering I had neither venting nor my vented windows in. One thing I took advantage of was to pull the fridge out of the van, attach to shore power, and kick it on Turbo Cool to bring it down below zero. Then I threw it back in the van where it hardly ran for quite a while. I'm really liking this setup. Pulling ice cream out of the freezer following a 6+ hour, 120 mile race was darn near priceless. Even after 40 hours with only a couple hours engine run time, I haven't seen my battery voltage drop below 12.3.
My Stark Power 125ah lithium battery is still AWOL, ordered a few months ago, hoping that it will show soon so I can finish out my solar and house battery setup.
I had a CRL vented window installed last week. No trips in since the install but it looks fairly nice and should really help temps in combination with the roof vent I'll be installing shortly. Still debating whether to add a vented window to the sliding door -
Yesterday, about $1200 worth of 8020 showed up and I'm working on my panel bed now. I went all black ano. Crossing my fingers that the design I came up with will work.
Lastly, for now, everyone keeps asking about mileage. All I can say is don't go racing out to buy a 4x4 Sprinter to save on fuel. Big tires + 4x4 + high roof + a bit under powered = crappy gas mileage. I have seen 16 and 17 for flat, slower trips but driving up around the speed limit gets ugly, especially when there's any wind.
