No experience with the Aria, but with the slides. The one big message on these slides is making sure that there is support rollers under the slide. And plenty of them. For some reason Schwinteck assumes that the mechanism can support some of the weight of the slide and this is just not true. The larger the slide out the bigger the load. I replaced both of mine with Vroom (about $4500 in Tucson, AZ) and they work great.
