If you buy one with some cabinetry -- make sure they're DRAWERS.... And I personally found almost nothing useful with the overhead cabinets. Not much fit up there... The drawers held all manor of stuff.
I carried a very tiny air compressor -

because my 2000 watt Honda would not start the "pancake style" (the type framers use for nail guns) version I have... the start load was just too much for it. LIGHT IS THE NAME OF THE GAME HERE... you're having to carry and store this stuff.
The light little Honda 2000 was/is a gem. I can make a pot of coffee -- charge a battery operated tool - run a battery charger -- lights - etc. Used it all the time.
Speaking of lights --- you see trailers with the big built in Halogen lights on the sides... in 15 years I used mine ONCE! Seriously... they're never where you need them - unless you're a professional race team in the pits... Portable lighting (great flashlight) is far more useful. Or use the little Honda to fire up a drop light.
Go to PITPAL PRODUCTS.... and deck out your trailer with strap hangers - jack storage - and anything else that needs to be stored. I love this stuff!

These folks CALL YOU AFTER THE SHIPMENT TO SEE IF YOU GOT EVERYTHING AND THAT EVERYTHING IS ALL RIGHT! Amazing.
And go to and watch the videos of how to do things right at at Mac's Custom Tie Downs!

I buy all my tie down stuff from them -- great products -- and the videos of how not to do things are most helpful.
