We took a SO Redcliff with bug netting and an SXL stove out of Bethel with Renfros in 2018 as well. We, like many others, bought the cyclone knock offs via amazon and they worked great. We had 4 of us, and two of us slept in the tipi and two slept in a 4 man hilleberg. We wanted a “backup” shelter if one of them had a catastrophic failure. It worked well. We used the tipi to have meals together and to dry out our gear. In Alaska, that stove was well worth it and really helped with moral. Mosquitos weren’t as issue for us, but as many have said, there were a fair amount of spiders. We took cheap Walmart tarps for under our cots and they worked fine. But when I go back I’ll take some tyvek as it is lighter (but wash it a few times so it’s not so loud) and would work just as well. Small changes I personally would make, I would take a lightweight bivy to keep all my stuff together on top of the cot and to keep the spiders off me. My brother ended up with an infection in his knee from a spider bite up there. Other than that small hiccup it was great.
One small note about my experience up there. All of those outfitters charge about 1k for rental and food. When we sat down and did the math, we could buy a lot of new and better gear, and way more food than they were offering. The only challenging was getting it there, but some Rubbermaid action packer totes took care of that problem. With shipping costs, I was $200 more than had we rented gear, but I came home with a lot of new gear. If you already have some of the gear, and are willing to put in some effort, I personally wouldn’t rent gear. Your just not sure what you will get, nor are you comfortable with it. Anyway, just my 2 cents.
