Don't be so tough on AutoHome, it is probably difficult for them to just answer their emails. Personally, I don't like it when vendors monitor a discussion, it colors it. We are lucky we don't have to import these direct from Italy, you don't want to see what a box looks like if it wasn't shipped in a whole container. They have to crate the tents because our carriers in the US are so rough on freight.
Back to the discussion - Andrew, think of a RTT like you would a sleeping bag. It has more in common with a bivy than a ground tent. I personally have a Columbus even though I prefer a Maggiolina because this is my wife's preference. She likes the height for putting on her clothes. Me, on the other hand, like it when it is so cold you have to dress inside your sleeping bag. Yes, it is all about compromise.
If anything, I prefer the older AutoHome tents. They were full expedition tents, simple and tough. The small "Adventure" for example was really small, designed for cold weather and stayed toasty inside. Worked well in hot weather too, opened up and the fiberglass shell didn't transmit heat. Had a flat top and tie downs so you could throw crap on top of the tent. Which brings me to my latest "rant" what is with the ABS shells on the Maggiolina knock-offs? Isn't that a thermo-plastic, won't it reform and distort with heat? Maybe they are adding glass fiber for structure? Seems like a huge cost cutting shortcut.
For reference, I'm not a
big fan of AutoHome US, I do really like the guys in Italy at the factory. The whole factory shuts down for a month in the summer and everyone goes out and "tests" their tents, seriously. Years ago I talked to their office manager, who spoke English, and wasn't taking her advice seriously, and she set me straight, she and her husband used one of their new model tents in Northern Africa for a month.
