Hi.Something I just learned a few months ago is that tents, even ridiculously expensive top of the range canvas tents have a certain amount of life measured in weeks. eg to quote from one of the de waard tent forumsI would like to setup the tent, and leave it for the whole summer while works going on. So, something more solid and robust tent would be ideal. Looking at the new 3 sec. setup tents in Amazon and eBay, they didn't look too strong to last for long time.
I have not seen the inflateable fram tunnel tents before, so will have browse for them for the price and how they work.
I had a vintage canvas tent for the scouts a few year ago, and setup at the corner of the garden for wood carving works in there in the rain. They were heavy, sturdy and good, but was bullky to store and tricky to set up, and take off fold. They could be more expensive than the plastic tents. If parts were lost or broken, it was difficult to source them too.
' A De Waard has an expecting life span of around 45-50 camping weeks (15+ years of camping 3 weeks a year)'
I think this is because of the damaging effects of UV. Something you might want to consider-most camping tents are not designed to be left standing for many weeks/months at a time. The life expectancy of a synthetic camping tent would be shorter I imagine. I have no experience of this ,it's just what I have read, so I may be wrong.
Also,I am not sure what happens when a tent has too much exposure to UV.
I know you can buy tents that are meant to be left out all summer or all year but I think they use different material to leisure camping tents and are consequently quite expensive.
