First let me say, Im brand new to this business so Im not sure my decisions will be the right decisions.
I was doing research to build my first trailer and made a list of my needs. After much thought here is what I decided on:
14 foot enclosed v-nose trailer with barn doors - I decided on enclosed for several reasons...Im in PA and decided this would solve my winter storage problem. I also travel on dirt roads and figured it would save wear and tear on my equipment. And last and probably most important, its a giant billboard. For about $1000 I did a wrap on both sides and rear that look great. I feel this makes me stand out and look professional.
3000psi/5gpm hot water skid - I decided on hot water to allow for future jobs cleaning equipment, hoods, etc. Figured I would just add hot water from the start.
325gal buffer tank - I have a hudson float valve set at about the 75 gal mark. This is what I carry most of the time to save weight. If however I need more water, I can just fill up the tank.
Two hose reels mounted on the back of the trailer - one has 150 feet of pressure hose. The other has 100 feet of water hose hooked to the hudson valve. I carry extra hose if needed.
Im down streaming from a 5 gal bucket at present but plan on adding a chem tank as business improves. Im thinking 15-20 gal
The front of the trailer has plenty of room for my surface cleaner, extra hose, brooms, brushes, and chemicals. I found milk crates screwed to the floor make a great way to carry everything. They hold 4 gal bottles of various chemicals, a 5 gal bucket and lots of extras. I also screwed pieces of PVC pipe to the walls which hold my wands, etc.
Hope this gives you more to think about. So far my setup seems to be working great but time will tell. Good luck with the setup. Let us know how you make out!
