Seems like you are doing due diligence. I would suggest that if you are not in a big hurry, which it sounds like you are not, take a look at the used 5th wheels in the type you want. There are MANY!!! Let someone else take the hit for depreciation. If you want to buy new, just beware that from the sounds of it, prices are coming down. I would get an inspection done on anything you buy unless you are comfortable doing it yourself. I spent 4 hours going over ours before I signed. Look behind things like the trim on the backside of the slides. That is where I have found the only faults so far. You have to remember that this is a house going down the road at 60-70MPH and they take a beating. Thing are going to come lose and things are going to break. If you keep that in mind, you won't be disappointed and blaming the manufacturer for faults. Some but not everything! Enjoy! It seems like the Alliance family kinda hangs together. We have been very happy with our 2025 32RLS so far.
In reference to your soft start question. I'm not sure if they use Furrion Chill Cube air conditioners on all their products or not but you will not need a soft start on a Furrion. They spin up very slowly and draw minimum amps. Can't remember the amperage but they both will run at less than 30 amps when compressor kicks on. I can run both my A/C's on my Predator 5000W without a problem. Can't say what else I can run at the same time as have never had to. I attached my Gen Set (100lbs) in my rear hitch with a reinforced basket with 2" hitch welded to the basket. Stays there and just crank and let run at least once a month. Cord reaches so don't have to worry about moving it. Works great. The solar is enough to keep batteries fully charged for the fridge.
