finally taking some time to read the advice offered thanks. I'll try to cover several comments:
Wmlayton, Alweld boats are pretty popular around the state. I've seen a few on the Kuskokwim. There may be one or two around Dillingham. But buying a boat and putting a cabin on it is way out of my budget and would interfere with using the boat for poking into sloughs etc. I think a few folks do just as you suggest on the Yukon and Kusko but I've heard some of those folks tow a smaller boat or canoe to get around. I have toyed with the idea. Around here quite a few of the commercial fishermen take their 32 foot gillnetters up various places and live aboard them - nice option. I've posted a photo of a friend winching a whole moose aboard his boat. Thanks for the thoughts tho. And I agree those alweld are tough.
Bilmac, thanks for the review of the Alaknak tent. Cabela's has one on sale now and I've been real tempted but was concerned regarding the very problems you mention. One problem we have here too is if I tent on a "sand bar", more often its a gravel bar and very hard, hard to put down adequate stakes and hard to find a big flat area. Get off the bars up on the river banks and wide flat spots are more scarce unless I use a vacated fishing guide camp - which I do often.
The more I thought about it, the more I think finding dry fire wood or keeping wet wood lit might be a hassle I don't want to mess with.
I got to reading the fine print on some of these Mr Heater Portable Buddy type heaters that use propane. I see some have special oxygen sensors to make them safer in a tent. This might be an answer that I could use in my current tents or in a screen tent I'm considering. Light weight, compact and should run a while on a 11 or 20 pound propane tank. We usually carry propane for lights and stove anyway.
Gun Runner, thanks I'll check out Sportman's guide and see what they have. I've always been a bit wary of that outfit. Seems some of my friends haven't always been pleased with the service or products there. But I'll check them out.
thanks all for the suggestions, I may hit on a solution yet.
