Rave, that's a shame about your Jeep. I hate automotive wiring, the logic behind it always boggles my mind. I'm fixing up my Jeep one problem at a time. I got the crankshaft position sensor replaced and now it needs a vehicle speed sensor...it used to be a speedometer cable. At least it isn't too expensive and I can do it with a ratchet and some cursing. The big trick is not having it hot from driving, but I seem to keep making post office runs to ship stuff which keeps putting it off.
Glad to hear you're doing better, Evie!
Terry, I have excellent results with a single fan on exhaust. The trick is to limit the air intake to one location or small intake in multiple locations. We may have an insulation advantage as well with a house versus a mobile home. Worst case, get a bigger fan! Finger, toes and eyes crossed that a house is in your near future.
The problem with me, money and construction is that I seem to keep running out of money before I can finish, then I end up redesigning and tweaking while I'm trying to come up with more. Then it just goes on and on. I finish it eventually, but it always takes me a little longer than I planned.
I have started the "Montgomery Scott" (Scotty on Star Trek) rule for estimating time to complete a project. Guess how long it will take, then seriously analyze how long it will take, add 100% to that then multiply by three. That way if I'm done sooner I feel better!
