Some things like tent vs bivy, are situational or just personal preferences. If mosquitoes are an issue a tent might be the best bet, if you want to ride all day and into the night dropping into a bivy is quick. Stove or not again personal, some people don't mind cold food even freeze dried, some are willing to carry the stove. The type of stove is very personal, price of fuel vs how often your using it, a small metal cup and a stick fire, assuming it's safe and legal, will get the job done. Clothing choices can very by forecast, also personal some are willing to suffer the cold to save weight. As to water, some can go farther with less others need to carry more, some ride spigot to spigot others need to carry the filter. Some routes don't have water to filter so more capacity is required.

Tim, appreciate the response. However, I think people have the misconception that bivys are only the bivy sacks. Im referring to a bivy tent, which has poles and such. Im not sure why more people dont use them, since they seem to just be a smaller tent. I posted the link to the one ive been researching in the original post, as well as one of the solid fuel stoves that seems to be well received.
I totally understand that all of this is on a per trip basis, and would obviously need research on the routes before I can finalize any of my equipment. I appreciate the time. For now, it seems that fire roads and very little singletrack is my current goal. Having a drop bar rigid bike is going to limit me as far as where i can go for now. Might have to EP a Beargrease or a Muckluck.
