I have a 2008 Chalet Alpine that I bought used. It has no wires hanging from the bottom. What I like about it is that it has the water tank inside under a seat, where it is somewhat protected from the cold.
It is small. I share it with my chocolate lab. I have the bunk floor plan. After many trips with it, I switched to sleeping on the other end--the dinette and will take the cushions off the "bunk" and use it for counter space.
I've had it in horrendous rain. I live in a very wet part of Washington the State. No leaks. I've pulled it down through rain on the Oregon Coast a few times. No leaks.
If you require storage, that will be a problem. I have the box on the front, which doesn't leak either, and that helps a lot. But I've learned not to put the dogfood in there. I've waked up to raccoons messing with the locks and jumping up and down on the box trying to get into it.
I can barely lift the roof. I use a notched axe handle to lift it with because I am short. They make electric lifts for them now. What amazes me is that everything keeps on working. I did have the back window recalked, before it leaked. I could see that the calking was wearing out. While camping in wetter than even here weather, there was a lot of condensation and occasional drips from the peak of the roof.
I don't have an air conditioner. It has a propane furnace and I carry an electric heater in case I'm able to plug in to power. I have the high wall model with a tiny freezing compartment in the fridge. I like having the ability to make ice cubes. A sink, hot water and outdoor shower are also on it. It came with a Thetford porta potty, which was still wrapped up in plastic.
It tows well--no problems there. I pull it with a 6 cylinder Ford Ranger.
That's it. I ended up with a Chalet because it was in Craig's list at a dealer. The Aliners look good. The Rockwoods weigh more, I think.
Hope that helps.
