Sounds like you want a folding camper, not a trailer tent, mine used to take me around 30 mins to set up on my own, the better ones have the advantage of having hot/cold water, shower, loo etc & you can even leave the beds made up, so just fold it out & you’re almost ready.
I went from a seasonal pitch with a caravan to the folding camper & hated it, if the canvas is wet when you pack up you have to open it all out again when you get home until it’s dry, having to leave site around 10- 11 am on leaving day & because you’re towing it’s not practical to spend the last day exploring the area or doing anything, so it’s a case of hitching up & going home in the morning wasting the last day.
We went back to a seasonal pitch & just move the van to where ever we fancy going after a year or stay where we are if it’s a nice place, pull up, kettle on & you’re ready to relax. It might be just because we went from being on a permanent pitch to towing but the hassle just made me not want to bother going away for a weekend & the folding camper spent most of it’s 18 months with us on the driveway doing nothing, now I’m away most weekends again & quite often go for a few days during the week when I’m “working from home” 🙂
We’ve even taken the van off the seasonal pitch for a week or two when we fancy a change & then put it back afterwards.
