Holy sagging water tanks, Batman!

Thanks for the reply. I'm thinking of building an aluminum framed single axle utility trailer and am thinking about what type of suspension would be best. The trailer wouldn't be designed for real heavy hauling and no long trips are planned. I like the ease of installation of the Torflex axles.

I hate to get too far off the OP's subject, but lightweight trailers are some of the hardest to get good axles for. I built a few trailers for welders and generators and getting a good axle is difficult. The lowest, decent, axle is in the 3,000-3,500# range. Usually, below that the spindle, hub, and axle are junk. My welder/generator trailers were going to be in the 2,000#+ weight range. If I used a leaf spring single axle rated at 3,500# the trailer would bounce down the road. The rubber torsion axles ride better and are more forgiving once you get them loaded to about 60% of their weight rating or higher. What I did is buy 3,500# Flexiride axles and had Arizona Axle install the rubber with the center part missing. That gave it the stability in the tube that it needed, but the "give" required for a 2,500# rating. I had the best of both worlds, a quality axle, and it rides really well. These trailers are an example of where the Flexiride brand payed off because I had to adjust the ride height on the trailers.
