    sir I read all your articles and understood most of it , I have a 5×10 utility trailer with wood on the floor I’m driving to texas, so my question is , if I place 80lb bags of cement in the center of the trailer in front of the tires but not to far to the front will this give me more stability, or should I place one bag all the way to the front and follow it to the center of the tires and stop there for better stability , also I’m going faster 65 to 70

      Good questions. If the tongue weight — the force from the trailer tongue on the hitch ball — is in the area of 10-15% of the total trailer weight, it should be good. There is more than just weight balance in the stability equation, but that’s a big part of it. If you have a choice, like with bags of cement, then low and in one tight group is a little better for bounce (as opposed to spread out all over the trailer), assuming the weight balance is exactly the same. That said, it’s not really a factor so much with stability. Enjoy your trip.

    My dad wants to have a flatbed trailer that he can use to carry things when he goes camping. It was explained here that the trailer bounces when the suspension is too stiff. Furthermore, it’s recommended to go to trusted suppliers when planning to have a flatbed trailer.

      We design trailers and we offer the plans for sale so you can make them. The widest legal for highway use is 102″ width (8’6″) state to state. Your F-150 has towing limits (total trailer weight and tongue weight), so build your trailer below those limits.

    My husband want to get a utility trailer for his motorcycle, and your article had great tips to help stop the trailer from bouncing if this becomes and issue. I liked how you said to consider lowering the tire pressure so the tires act more like a partially filled basketball and bounce less. Thanks; I’ll share this with my husband if he gets a utility trailer.

    I had no idea that a utility trailer could bounce when it’s empty because there’s not enough compression to keep it down. Right now I don’t have a trailer but I think that it would be important to look for one that is right for the loads you plan to carry. We like to go camping a lot so I’ll have to figure out what the weight of our equipment is and then look into utility trailers.

    Hello and thanks for the info.

    Would welding in some shocks help? My trailer is homemade with an old pickup axle on leaves.

      Shocks are not often used on trailers, partly because the suspensions don’t move that much. However, a pickup truck has much longer springs, and they do move a lot more. If your trailer has the pickup truck springs, shocks might help a lot.
