Just seen product videos. Personally, it seems to be a lot of mulah for something you might use a few times. I would get a small enclosed trailer for the same price, as it can be used for other things as well. Plus you can put your luggage in and all will stay dry. Trailers are easy to resell also. JMO. :Coffee:
With no personal experience with either these but having watched the YouTube videos the triple d seems like a better lift. Including its attacnment and ease of removal.
