Hi wok welcome
Generally speaking, the used market is where you will find bargains.
Make sure the basics of the CT are good, worry about the bling later. You need to be able to get there and back, and setup and pack up without causing a divorce.
I would suggest that you look for a good name brand, older campertrailer as your 1st purchase. You will learn heaps about what really suits you without investing heaps.
As an example we bought an Outback rear fold soft floor as our 1st camper. We learnt heaps and sold without dropping to much cash. We then bought something we expect to last a long time.
If you want more specific opinions and advice then provide details of things like, where you want to camp, how often, towing vehicle, budget etc. It will help us to help you.
Cheers
