I reckon most soft floors once the trailer is unhitched, legs down (as with any trailer) most wouldnt take much more than 5 mins for the tent to be up.
LS had a video of the explorer + being up in 1 min once legs were down and travel cover undone with 2 people..
Yeah we had a LS 360 I think it was.
Putting up the main tent section without the annex was pretty quick. But thats not where the time is. We used to pull everything out of the trailer first, once it was in position and levelled. Pulled everything out before the tent went up cause it was just sooo much easier than climbing in after the fact.
Then set up stretchers for the kids, the main bed, the kitchen, water, gas, set up bbq, tables, chairs, lights. get the fridge outta the car, plug that into your trailer power.
It seemed like it was never ending at times. As stated previously, everyones setups are different with varying levels of accessories.
We moved to a conqueror and most stuff stays in it now. never looking back, ill go to a caravan no worries when the kids no longer want to come a long and we get sick of having to setup the portaloo nad shower
