We have a rear fold and it is easy to set up for overnighters with out unhitching. We have a prado, so access to the rear is a bit tricky. Some forward folds would not allow allow access when hitched (even during the day traveling), same could be true for any camper with shorter draw bar/clearance.
I have seen people with a jayco not unhitch for an overnighter, however not be able to set up the end closest to tow vehicle, which I would think is less than ideal. There are some people that try to NEVER unhitch, if this is you you need to get the right setup.
So depending on your vehicle/access and how you intend to use your camper it it might be worth considering access. I saw a forward fold on a ute that was a good match for access, however if you travel straight to the place you camp for 2 weeks access to vehicle would be less of an issue.
I hope you can find some to hire, or visit a camp ground/caravan park and see how others are using things and setting up.
good luck
