If you go the Build yourself route.
This may be an option for the trusses: (I have never dealt with him).
http://jackson.craigslist.org/mat/1381235312.htmlIf close to Gulfport area: This might be a deal
http://gulfport.craigslist.org/grd/1379490290.htmlIssues we have had with this.
1) Mold
2) Rats/Mice chewing on bare wood(studs).
3) Waps/Hornets calling it home
4) Snakes seem to thing good place to hang out
5) Squirrels like to get inside. (maybe the reason for the snakes)
6) Because it is in the woods, It seems to draw the attention of everyone tresspassing. (Oh they have a building, I wonder what is inside).
(Always finding beer bottles, condoms, etc... in it.) A whole bunch of cigarettes put out on the floor. (Glad it did not burn down)
As mentioned, another consideration would be a trailer. Not necessarily a camper trailer.
A hunting partner, bought an 8 x 12 enclosed trailer.
Ran wires thru it for power boxes.
Then installed a gas/propane stove on the wall With gas line/valve outside where tank is.
Mounted a roof AC (like campers have).
Has roof mounted vents, and small slider windows on walls for venting/air flow
Added an Awning like campers have. (screened in) ( Nice for when cooking on propane/gas stove, and it is raining)
Found a Honda (very quiet Generator) cheap, and it runs everything. (If we need it).
Best of all, it hauls all the Hunting Equipment (stands, atvs/rhino, coolers, chairs, etc...) inside, and don't look like the Beverly Hillbillies going down the road.
Has become very practical for other uses. (Tailgating parties, etc...)
I think he has $2800 in it total (He bought new).
Can sleep 4-5 in it on cots very comfortably (Minus the snoring/farting)
