Well it's a 4x6 trailer. I have a 100 gallon water tank, big generator, vacuum and my pressure washer. With all the products very well organized. I do use my trunk as well. Now it all depends, it's about 2k pounds if I feel up all the way with water but I normally don't do it. I put about 50 gallons which for me is sufficient. Yes having a HEMI does have its advantages but still, you have to be very careful how you drive specially with that much water in the back. Not the perfect car to be hauling a trailer but I like it this way, I get a lot looks and compliments every where we go. The trailer itself is very light, very well built and I can see just fine on the side mirrors of my car which is perfect. When I have time, I will take a picture and show you guys how the trailer is inside. I am adding custom diamond plates on the floor and custom building a few shelves myself this weekend.
