For the past twelve years, we have been using a 5-foot by 8-foot enclosed trailer when attending rocket launches. It has served us well, but we had started to outgrow it. So, we recently invested in a new 6-foot bv 10-foot trailer built by Diamond Cargo. We researched our options and shopped around before deciding to purchase the trailer from a local dealer.

In addition to being a little wider and longer than our old trailer, the new trailer is taller and has a "v-nose." The interior volume of the new trailer is about twice the volume inside the old trailer.

We've been working on the trailer for several months, but I only recently created this Build. So, while the entries are appearing soon after each other, it really took us a while to complete some of the steps.

When you purchase a new enclosed trailer, it is pretty much an empty box.

The first thing I did was to paint the walls inside the trailer and apply an epoxy coating to the floor.

I replaced the trailer jack with a The Ultimate Trailer Jack. The new jack has a couple of nice features.

First, it has a release pin that quickly drops the jack tube down. This makes it easier and quicker to lower the jack.

Second, it allows you to raise the bottom of the jack higher than you can with the original trailer jack. This gives you a few more inches of clearance when driving over a bump or through a ditch.

The next thing we added was a fold-out RV step to make it easier to use the side door. The step bolts onto the frame below the door, but the bolt holes didn't line up with the frame on our trailer. So, I used an angle grinder to create copious sparks as I cut a piece of steel angle to fit between of parts of the frame. I bolted the steel to the frame and the step to the frame and new piece of steel.

Next, we added a grab-bar handle beside the side door. The RV grab bar that we used folds flat against the trailer when not in use.
