It looks like a really nice trailer. I looked to see if there was a Holiday Rambler dealer near us when we bought our Winnie, but there aren't any dealers near us. Rear kitches are known to take a bit more bouncing, but I think you can take measure to prevent any problems such as removable security bars and packing dishes accordingly. Holiday Rambler procucts were known to be pretty good but I haven't read anything lately. Personally, unless other information comes up, I'd lean towards purchasing a HR product before a lot of the stuff that's out there.
The best thing you can do is really look it over carefully for the quality of the construction, and how it compares to any other trailers you would consider.
Since I'm very happy with our Winnebago Minnie 2201DS...but we just got it...I recommend comparing the Aluma-Lite to a comparable Winnebago model.
After looking at the HR web page and product brochures, it looks really good to me!
