You can sleep within a couple of feet from the small Snomaster, Even if you are awake trying to get to sleep they run that quite getting to sleep is not a problem, I am a light sleeper and the slightest noise wakes me, Other fridges really annoy me when it comes to getting asleep but not the 35L Snomaster, nothing comes close in that respect when it comes to the lack of noise.Can you sleep near a 12v without getting woken up by a cycling compressor?
This depends on the person. Some people can sleep through almost everything, while a drop of a pin wakes up the next person. Mothers can here a baby roll over in their crib in the next room and sleep through a barking dog outside of their window.
Living on a ship with with constant noise around you, many people adjust to the noise.
My truck record was 9 days in Death Valley. My river record was 17 days, limited by the fact that that is the longest river trip I've ever done. It's not uncommon for people runnning 21 days in the Grand Canyon with cold beers at the takeout. Some day I'll write a post on how to do coolers but a good start is Mountain Buzz. Think river trips. Lots to learn from river theory in all aspects of overlanding. I personally think a combo of small freezer and medium cooler could get you to Tierra Del Fuego and back in style. Only practical way to enjoy ice on the road is to carry blocks, keep them out of the water and keep the air moving. Making block ice mobile is a problem I'm working on currently.No ice chest used for food or beverage consumption is going to keep ice for a week. They will keep meat cold that long if everything is sufficiently chilled and the cooler is not opened. If you have to open it 6 times a day to eat, forget about it. 3-4 days, sure. But you still have your stuff sitting in a slurry. And cold packs do not keep stuff as cold as regular ice since you can't pack them around and among the items as well.
I must have been doing some thing wrong, using the 2x50 watt Renolgy panels, or the mini system or multiple 75 watt panels etc. etc.; I got/get reduced output output with as little as 30% shading of the panels; resulting in having to babysit the solar and moving it every 45 minutes or so to keep adequate sun exposure... my preferred close camping (Pike National Forest primitive sites) might have 20 percent (often less) solar exposure (80 percent shading).I can sit in a partially shaded spot and my solar will run my stuff indefinitely.
