We have a lifestyle walkthru, which was the first of the genI, genII walkthrus. Ours has chinese canvas on it but I am under the impression that the new models now have australian canvas.
Like Amimall our camper is also very heavy, though there is not a great variance compared to any other option that would suit our situation (these options are still campers not caravans)
My husband and I have setting up down to an art, tent itself usually around 10 mins and annex around 20 mins. We also have issues with water pooling/dripping in the annex if it is raining, even after we added extra spreader bars.
Also be aware that the tropical roof works great but due to the material used, tends to start breaking down and needs to be replaced. There is a thread on here regarding them. Our tropical roof material is fine, but for some reason the fiberglass rod above the bed keeps snapping - this has only started happening in the last 18months.
Also unless they have changed the travel covers, they are very tight. We didnt get the mattress from lifestyle, we used one we already had at home that had no pillowtop. We also put two 4WD mats on top of the mattress, however because our mattress didnt have a pillow top (and was a bit of a sad specimen compared to the one lifestyle use) the entire depth was not that much deeper than had we bought their mattress and had no mat on top - maybe 7cm extra. In the end the zipper burst and we ended up getting a new travel cover made up and now instead of it taking upto 20mins to get the cover on it takes less than 5mins.
We are happy with our camper, it is well built, tows well and doesnt have a tendency to break. The biggest disappointment has been the tent and as stated above I believe it is now an Australian made tent, possibly of a different design.
When we bought our camper we were after a walkup version and at our comfortable price point the only choices were Lifestyle or MDC, even 2nd hand units were still going for over 17K.
While I have given you an overview of the negatives, there are a great many positives and we are happy with our camper.
