I'd suggest hiring a few trailers for weekends to see what you like/dont like and what you NEED over what you think you need.
Theres plenty of options out there, actual caravans, campertrailers, hard floor, soft floor, forward fold, rear fold, Hybrid trailers - all have their + and - and also some suit different travel types more than others.
what sort of camping do you plan on?
Overnight/Weekends/hitting the road, base camping, on road or Off road, outback travels, caravan parks
theres several caravan/camping shows out there depending where you live...
Remember you don't need to spend $50,000 to be happy and comfortable out there...
