Tonight I'm going to start fixing my storage box. It had some minor water damage when I bought the PUP and the PO told me that water was getting in but he didn't know how.... after a year, I haven't been able to figure that out either. I suspect there could be those famous hairline cracks underneath the hinge (I went into the storage box a sunny day, closed the lid and couldn't see any light coming in ) and there is also the side access door, I have to say that most of the times I don't fully close it when its raining (I don't like that the door needs to be key locked to be able to fully close it). The water damage is where the side door is but I've found water all over the stuff stored in the trunk. I'd like to know which would be the best wood to use, available at Lowe's or Homedepot, I'm not planning to go on a manhunt for some fancy marine type wood. Also, has anyone though of sealing the joint between the walls and the floor and adding some sort of floor drains? This in case water comes in again or there is a spill, at least the majority of the water will get out. For the side door, has anyone added some sort of visor that will keep water away? (something similar to this http://www.amazon.com/LT-Sport-serial-Window-Spoiler/dp/B00HI5XX9A/ref=sr_1_1?ie=UTF8&qid=1413388225&sr=8-1&keywords=rv+door+visor). Any recommendations to replace the annoying door lock? Thanks in advance !
