Welcome to the forum.
Oh boy, decisions, decisions. My first bit of advice would be to go and have a look at, over, under and everywhere you can, at your possible choices. I would not be parting with my hard earned without giving them a really good going over. Then when you find one you like, ask if you can have that particular CT. I've heard a few stories where the showroom model has been tweaked to look mickey mouse and the actual CT delivered has more than a few issues.
Also don't expect to get a Rolls Royce CT for a Great Wall price. You will have to make some concessions. Be prepared to fix a few things and treat it kindly. An imported CT will not take the punishment that a good off-road locally made CT will. But having said that there are heaps of folks on here who are more than happy with their imported CT and I am sure it will do everything you have planned for it.
My only other comment would be the size of the tent and annex. Wow, the Toptrail is huge. Bear in mind our 12' tent (18' overall) has just fitted on some CP sites. Free camping is another matter and the size will not be an issue.
Good luck and look forward to seeing what you get.
Happy camping
