This is my first time. I have an enclosed trailer and love it! It helps me keep everything I need cleaner and orderly. If you get an enclosed trailer make sure it is tall enough to walk around in, without bending over. I bought one with a drop down ramp in the back which is great to walk right in and grab the hose on the reel and walk out. Make sure you can exhaust out the top or back so it does not build up inside the trailer. If you have any questions about my trailer I would be glad to answer them. John with Ertl Power Wshing
