Hi, we have a Camplet, it really is really easy to put up and down, much easier and quicker than other trailer tents, but it is also much smaller than lots of trailer tents so probably no good if you have more than 2 kids. The tent bit (excluding the bedrooms) is just big enough for us but not massive IYSWIM
My views after 3 years of use - quick to pitch although we still spend ages faffing around setting up the inside, my husband can and does put it up by himself sometimes, but there is a fiddly bit with a pole that i struggle with. If its raining though it can be up and watertight in 5 minutes, the rest is inside and then pegging. Sleeping on the trailer rather than the floor - 2 double beds and its very cosy and comfy. integrated gas hob, the kitchen just swings out from the end of the trailer. Storage - you can store some gear inside it, we have all our pots, pans, plates, cutlery etc, water carrier, larder cupboard, table, clothes airer, laundry basket, ground sheet, carpet and toaster in ours. Still need to have bedding, clothes, toys etc in car, and we strap the chairs plus 2 bikes to the roof of the trailer. We also have a storage box on the frame of the trailer that takes the fridge, gas bottle, and a load of other stuff so basically all the camping gear except bedding is in or on the trailer.
Easy to tow, very stable at 70mph (although naturally we never go that fast...) The tent itself is very good quality and we have noticed that being canvas, we stay cooler inside in the mornings for a while after people in synthetic tents have been driven out by the heat. Designed to cook in 9proper ventilated kitchen area is a bonus.
Remember to factor in insurance to your cost calculations.
