2023 Aluma AE7.5x18 Rare find. THIS TRAILER HAS NEVER BEEN PULLED. I ORDERED ThIS AS MY DEMO FOR THE LAST RUN OF ALUMA CARGO TRAILERS. IT HAS BEEN STORED INSIDE SINCE IT CAME TO THE LOT. An Aluma cargo trailer will be the best pulling trailer you will ever own and you can never get a new one. This trailer is titled so we cannot advertise it as new. But it is new! Interior height is 84" and the rear door opening is 84".
