I'm going to spring a few bucks for a pump kit and generators before I go camping this year. It's been collecting dust for a few years while I was messing with propane. No rust at all and I have certainly not babied it any.
If you can find it, try trioxane fuel tabs. Not messy like Esbit tabs. It's good to have a simple and small backup in case of the unexpected and for heating something in the tent vestibule when hunkered from bad weather. Ebay, Amazon and military surplus stores are places to find trioxane.
I've been thinking of getting a small battery lantern this year mainly for tent use. I've been using the headlamp only for quite a time. I don't want a larger one for general area lighting because I don't want to put that much recharging load on my truck battery as i tend to stay put for awhile when I find a nice place to setup camp. So, the truck is not operating for a number of days at a time.
I have some trioxane tabs and a little folding stove for just such times, but it’s like the space blanket I also keep handy, for emergency use rather than everyday.
That Marmot looks like a nice tent. I have an old REI tent (1987) that’s similar, and a two-pole Kelty that I bought for last deer season because I hadn’t replaced the bent poles of the REI from a blowdown one night (I have since then; Tentpole Technologies replicated the old ones). I like the Kelty, but we’ll see how it lasts. Probably long enough, since I’d have to be still out camping at 98 to match the REI.
