I have beating around the bush for some time to do the fence post holder for our sewer. So finally had some time off and put it all together yesterday.
Overall I am very happy with how it turned out. I will leave it as is and if the white bothers me I'll paint it black to match the trailer. I mounted it just forward of the midship jacks to allow for access to the jacks. I did not put it to the rear since the tanks are there and I did not want to risk dragging it.
I was able to get all that I needed, including the fence post, at Lowes. The cost was just under $70 for everything. I was going back and forth on how to mount it and make the access doors. Stole a few ideas from other and put it all together..
Here is a copy of the receipt from the Lowes. It has all that I bought for this setup. Only two things were different and I will get to those..
Bought the 8ft 5x5 fence post and 4.5" gutter in a 10ft length. Made the brackets out of some 1 1/2" plate steel with holes pressed into them. Used my vise to make them. It actually was easier than I thought it would be considering I had only a hammer and the shop vise. Just took some patience.
I decided the leave the fence post uncut at the 8ft length. I would be just as wide as the trailer (It will stick out a bit with the caps on). I just cheated it to the driver's side a hair so it is slightly out on the driver's side to avoid the side of the road. The brackets were held up into the frame's lip using a few self-tapping screws.
The lid design I stole from someone who had done it before me. I Used the standard caps, two springs and four cotter pins per door. Used 3 1/4" x 1/4" springs and 1/8" x 1 1/2" cotter pins. As you'll see in the photos I initially mounted everything centered up.. But when the gutter was slid into the post the would get hung up on the cotter pins. So I moved them up to be above the gutter.
