Ezadventurer - Enjoy your camping about in SEA.
I'm back in the states for another month and then back to gallivanting about in the hammock soon in SEA.
Alcohol - I too went through your issues trying to get it translated, a horrific waste of time. Even using the proper Thai name for the product ended up with the locals getting confused. Most restaurants use it for keeping your Thom Yam soup warm when put on the table so that can also be a source of it for you if you’re desperate. I'm using methanol in the stove and it does put out a few BTU's less but beggars can't be choosers, haha. You can get containers of the methanol in the paint section of your local hardware/paint supply place. If you're in a large city it may have a home improvement store named Home Pro and they carry gallon containers with English on the front of the container underneath the Thai script. The container is blue and white in color and a rectangular shape. I wouldn't even bother asking the staff when looking for it as you will most likely end up frustrated, just nose around on your own. I've tried using the local moonshine booze Lao Khao and Lao Lao but most of the time it's not pure enough to ignite.
Mosquitos - I was camping in the Cardomom Mountains in Western Cambodia where those darn malaria infected and drug resistant mosquitoes can be found. I just use long sleeves and pants come 5:00 PM and so far have gotten lucky and not come down with malaria. Though getting Dengue fever two times now is making me a bit more nervous of the buggers.
Most of my equipment has been sourced in the states; the locals as you know need next to nothing, and laugh when they see my camping rig unrolled. Due to lack of demand by the population sourcing high end, specialized camping equipment locally is quite challenging. There is a gent in Chiang Khong that puts together a hammock that converts into a tent and is halfway decent. However it’s much too bulky and heavy for my needs. Carrefour has a camping section where SilNylon tarps can be found along with poor quality synthetic sleeping bags and camping pads.
Enjoy your camping.
