Welcome from Alaska, left Utah 35 years ago and never looked back!
Stable loads were my first addition, transferred over from the previous truck a SRW, hands down the best most useful cost effective mod period. Empty they keep the over loads from the empty banging and loaded they cause the spring pack to work that much more effectively, engaging them earlier.
Also have airbags which I feel offers a greater range of adjustment as well as provide some dampening effect to the heavily sprung rear end. I don't really need them but I'm glad I have them, with the heavy camper loaded I'll have 15 to 20 psi in them.
I see they have lower stable loads now which engage the heavy bottom spring. I may try them also, again for the adjustability.
