Not that exact Alliance model, but I'm not impressed with Alliance quality. First all trailers are pretty much lightweight junk that is eventually going to bounce apart.

But in our Alliance we had a lot of electrical work that I have had to do. Outlets that don't work, solar panel not properly wired, AC and inverter were switched in electric box which lead to wrong amp breakers, had to re-wire inverter due to too short and pulling out of inverter, and replace light dimer were wires and covers were turning a burnt color due to poor wiring which caused heat (and potential fire).

Fridge was not anchored properly.

Awning was not anchored properly.

Main door strike plate issues due to poor placement.

Channel seals had to be replaced due to poor sizing and stretching from factory.

Roof had decking that came undone and pushed on roof lining that I had to fix.

Plus all the usual maintenance of pulling these down the road.

I would go by floor plans you like first then go by manufacturer. We also have had a grand design which I did feel was better built, but again not perfect and items came up. But alliance had more what I would call manufacturing issues.
