Our first TT was a Skyline Aljo and we LOVED it
It was built very well, the walls were sturdy, the materials in the cabinets were strong and solid, as was the sofa and dinette. Only problem was we really out grew it.
No sure about the model you are looking at, but for the make of Aljo, I think you have a good quality product. If I am not mistaken they have a pretty solid construction too. I think I remember the dealer telling us that when we purchased ours.
I think in the other boards (Owners Forums) they have a group for Aljo owners.
Good luck and welcome.
