We upgraded our tenting to a
Big Agnes Big House 6 last year. Been mostly happy with it, but one of the main poles inverted on us under heavy wind last year. In those situations, you really have to run out every guy line available (which I hadn't at the time). I was able to recurve the section of pole that started to bend and all is well. I added the vestibule attachment recently and it's nice to have in rainy situations.
Before that we upgraded our air mattress to the
Kelty Sleep EZ version which is non PVC. I think its a poly coated fabric, with the fabric on the outside, so no rubber squeakiness to it. Also it packs down to half the size and weight of the average vinyl ones. Our previous vinyl one had the flocked stuff on it and it was hard to clean. We open up two full size sleeping bags to go on top and sometimes insert a wool blanket under that.
I'm on the propane train as well and have a 10lb bottle I keep in the trailer. It generally lasts me a full year of camping and only cost $8-9 to fill. If you connect one of these to a Coleman stove make sure you get the hose that's rated for the higher psi. If not, then your high pressure propane tank will cause oil to form inside the hose and clog up your brass bits. Also, I use a filter between the brass armature and the hose. For some reason my particular stove will not even operate without the pressure reducing filter inline. On cold trips we'll connect the tank to a
Mr. Heater Buddy and not have to worry about the 1lb canister running out in the middle of the night.
I've been using a
rolling tool chest for my chuck box and it's been pretty good for us. The main compartment holds the pots/pans, tongs, cutting board and the removable tray holds utensils, spices/salt/pepper, etc. Seems they have gone up in price. I paid around $45 for the one I linked.
As for packing, all the gear we have goes into various shaped Pelicans we got 2nd hand over the years. Then these go in the trailer. With just two of us and no kids, we have plenty of room for all the cases, couple of
Alps Mountaineering tables, folding chairs and spare parts.
