I have an aluminum Look Avalanche 7x23 inline. It is definitely a cheaper trailer, but has a lot of nice features for the price I paid. The frame is most definitely aluminum, not steel. It has twin leaf spring axles and isn’t torsion. It pulls great and has all LED interior and exterior lights, fuel doors, brakes on both sets of axles & pretty sweet rims, loading lights on front and back. I’ve had mine for 4 years and no problems.
