I only have one underquilt so when I've camped with the GF she gets the top & under quilts in my warbonnet blackbird and I make do with a sleeping bag and a wool picnic blanket stuffed into the lining on my HH explorer deluxe.
If I'm camping in bad weather there's zero chance she's agreed to come so I'd have my proper kit so it works out well enough.
I did make an underquilt using this site from costco down blankets but the suspension never really worked for me on my HH.
please update us on how you get on, sounds like an interesting spot.
the ropes that came with my HH were ridiculously bulky compared to the tree straps and whoopie slings I replaced them with.
