1. The trip to Fresno to "fix" the leaky top the 2nd time.
2. The placement of the 2nd 4D. It could have easily gone under the EB with the first, but instead is cut into the wall and removes a whole section of storage.
3. The LED cigarette lighter flashlight. I moved it to my Jeep where the power outlet is key on, so it's only on when driving.
4. The position of the external plug for solar.
5. The replacement water fill valve that froze and broke again
6. Not doing the reflectix sooner
7. The Lightforce lights- they're big and practically useless without putting more money into lenses, block the storage area
8. Not rerunning the hot water line before this winter
9. Putting sharp pointy aux light switches where I catch them with my knee occasionally, and also can't see them
10. Getting new tires without having a place to hang the spare (a 33" tire takes up a LOT of room in the van, and there aren't tie downs anywhere inside)
Well I had to stretch things a bit to come up with 10.
