A table saw is the power tool I've used the most. It's very helpful to cut customized sizes of wood. One of the very best tools, one I made, is a big 4-1/2' x 10' work bench on wheels. It's a back saver. I use it both in the garage and out in the driveway on nice days (when I make sawdust). A battery driven drill has been very useful (I have several). Have often used a Kreg pocket hole tool and a cheap Harbor Freight biscuit cutter for joining wood. A luxury tool was an air compressor. A pneumatic narrow crown staple gun is a time saving, fun tool, to use. A Ryobi disc sander gets used most days I work on the teardrop. A router has been very helpful for cutting and shaping a side pattern, the walls and doors. Will use it much more when it comes time to make cabinets. Hammers, screwdrivers, tape measures, level, straight edge, 4' aluminum T square, files, chisels, sandpaper, extension cords. An old office chair on wheels with the back removed to work sitting down and to scoot around. Good lighting. Help from friends now and then. T&TTT has been invaluable.

Andrew's teardrop plans and tongue strength information in the Design Library - thank you very much Andrew. Going to some gatherings to meet teardroppers and see teardrops. Teardrop owners who say climb in and lay down to see how you like it. Steve Tripp's Index. Joanne's Desert Dawg website. The Hall of Fame. Raka.com epoxy. A gallon of Titebond II to refill the little bottles. The DelCity electrical parts catalog. Amazon.com. UPS. A credit card. A comfy warm bed to dream at night about teardrops - sometimes problems get solved, or a good idea appears, in a dream. Mike and Chell. Aunti M's thirst for bubble oil and pictures. Madjack's sage advice. A digital camera. A computer. The Internet. Warm enough days to work outside. A garage. A sense of humor. A chair to sit in to rest and contemplate. Pencils. Sharpie pens. Blue painters tape. The world wide, growing, community of teardroppers.
What was the question? I seem to have gotten into a teardrop stream of consciousness.
edit. How could I forget clamps? Lot and lots of clamps.
