I have a Lifestyle Walkthru. We have had it 4 years and in that time have reduced the time it takes to setup dramatically. Our current setup time is half of what it used to take while we were still getting used to having a camper rather than a tent. It is almost always husband and I doing setup, we politely decline 'help', we have it down and know what each other are doing and what order we do it in.
Unhitch and level - Takes 10-20mins, depending on local terrain and wether or not we have any 'communication breakdowns'. (unhitch camper, move car, put down stabilizer legs, ensure camper is level, take off camper cover/ fold up store away.)
Put up main tent - Takes 5 mins. (main tent up, pegged out) Open tent off camper, we have a 12ft tent so we have to put in extra poles and raise end of tent. Go outside peg down tent.
Put up annex Takes 10 mins - (annex up, usually no sides, tropical roof pegged) Takes 10 mins. We keep our annex roof attached to the main tent to save on time and storage. We have all our poles clearly marked and kept separate from main tent poles to avoid confusion and while husband is pegging down main tent I lay annex poles out in place.
Bedding - Takes 15 mins. (main bed, 3 x kids beds, put on sheets/blankets, bring in pillows, bags, toys.) Main bed is almost always made up, kids beds x 3 depends on length of stay but we usually put up three stretchers and place self inflating matts on top (which we keep stored flat on main bed) Middle child usually takes control of the making of the beds while I go out and help set up kitchen.
Kitchen and dining - Takes about 15 mins (Floor down, kitchen out, table out, chairs out, lights up, tv out, water hooked up, gas hooked up.) We use cgear for floor, quick and easy to roll out and peg down. We changed our kitchen to a drifta DPOR, it takes a couple of minutes to setup and everything alrady has a place so I dont need to worry about unpacking pots and pans ect.
Total time average (keeping in mind that some of these things are being done at the same time)
35 - 40 mins.
Most of the reason that we got our time down is that our camper has evolved with us. When we saw a way to make it easier, then we would do the mod.
Eg. Fast connect water
Kitchen with complete storage
Annex roof kept attached (we never used to be able to do this but after the zipper busted on our cover, we had the cover replaced with a bigger one)
Setting up our electrical so outside lights only needed to be clipped in.
Keeping kids matts on main bed saves on packing/unpacking.
Small things add up to alot of saved time.
