So, do you want the brutally honest truth? And I can probably speak for most of us on this forum, to a certain degree.
It's not a matter of need, it's a matter of want. Most of what we purchase isn't needed, at all, but we WANT it. I fall right into that category with many of my purchases, not all of them, of course. I've owned multiple roof top tents, soft shell, and hardshell, have slept inside my Jeep, and now own an Ursa Minor top. I could have easily kept sleeping in my backpacking tent that I've had for years lol. However, after all of that, I wouldn't trade the Ursa Minor for anything. It's, by far in my opinion, the best setup for a 4dr Jeep Wrangler, unless you need space for more than two people.
Most RTT's are manufactured in China, by just a handful of manufacturers, built to specific specs for companies around the world. Some are better than others, some are marketed better than others, some are sold by companies with much higher levels of customer, and product support, so price is determined by a variety of factors.
With that said, importing isn't easy, or cheap. By the time a well known company gets those tents stateside there's a host of costs involved over the price you see on Alibaba, and that end landing cost is a lot more. On top of those additional costs those companies have a particular profit margin they're going after, depending on whether they are consumer direct, or have a wholesale division set up as well. This is expected, and rightfully deserved by the people that own these companies, since after all, they are in business to make money.
The range of prices you find on RTT's is generally determined by whether they are standard soft shell style, or hard shell. Hard shell is MUCH easier to setup and break down, MUCH! A lot of people are willing to pay for that convenience. Other factors are in the type, and weight, of ripstop used for the tent, rainfly, etc. Mattress quality can also vary greatly, and in fact, some RTT's now don't even come up with a mattress, so there's another factor than plays ultimately into the cost. And then in just general overall quality of construction you'll find a number of differences as well. Best way to see this is to look at a lot of them at a show. You'll see it for yourself, and then more clearly understand the price differences.
As far as what's best for you? Only you can make that decision. Like I mentioned, a lot of these purchases are based on wants, and not necessarily needs. Figure out what you think will work best for you and your family. Look at a variety of setups, in person if you can.
