Need Advice on buying Dry Van

I would just spray the roof with a garden hose and see if it leaks, as clean as the underside looks I think they have it sealed pretty good, if it does leak in the future it wouldn't take much to permanently repair this.

 

Rooftop patches are not always NICE LOOKING as no one sees it , but as Taildragon noted , do a leak test of your own.

 

"Taildragon" was very thorough helping you. The only addition I have refers to roll-up doors. I hauled Aluminum beverage cans years ago and those pallets were size to maximize volume. The pallets are left on the floor and slid into the trailer side by side. Roll up trailers have reinforcing on the tail to provide track mounting. This narrows the opening as compared to swing doors. Can plants and I'm sure others, need maximum width to load. Could not get the last 2 boards on because the door posts are in the way

 

Warhoop has good info , for generalized dryvan freight forget about ROLL UP DOORS

 

Good point warhoop, I had forgotten about the cans, I have seen glass bottles shipped the same way, as well as wide crates of machinery, and don't forget about the lost area at the top rear, you will lose six inches height where the overhead door is rolled up while you are loading, and like FLATBED said general drybox over the road freight nix the rollup doors.

 

That looks like a very good patch job. From the inside pic, I do not see and signs of water coming in. If you feel unceritn tho, just take a hose and water it down, that's all it should take to see if it leaks.
