Maybe a few more words on the Kemphaan. The Kemphaan has the advantage, that is has a nice bigger frontside roof (great for two big chairs) vs. many other tents in that size category. There is a chance in stable non turning winds and rain situations to live without an extra tarp with just maybe one windscherm. So in a one night application = two days, you may like that extra rain protection, especially in the UK
However, be ware of the 170cm height situation. When cooking, the slanted front roof will even make my wife crouch a bit, so when we take our Kemphaan for a 4 to 5 days trip "times" cooking, she dreams of our Goudplevier where she can stand up straight. We have the old Goudplevier with the lower front entry. The benefit of the newer Goudplevier, at least every time we visit Heerde, we find minimal, if not totally obsolete (my opinion). Many think different and prefer the new Goudplevier. Whether you can get a never Goudplevier with all options in your price range, can be a tough one.
If you (and your neck) can live with crouching when entering and cooking under the front roof, the Kemphaan has a lot of space due to the two front and back pole construction = shoulder width space. We feel you need at least one windscherm, maybe you disagree. With at least one windscherm the difference in pure setup vs. a Goudplevier, poles and pegs, becomes almost non existing, the more you add, especially for turning weathers. Goudplevier and Kemphaan are very close in poles and pegs. It is the small bag for a serreluifel, if both tents have two windscherms and two extra poles that make a (small) difference. Due to its "overhangs", the basic Kemphaan bag almost feels like a bigger tent. Our older Goudplevier does not have the extra mosquito door, so the tent bag feels equal to our Kemphaan.
As said before, there is in my opinion nothing besides a basic Kampmeeuw that I would dare to call a real one night 3P tent. A Kemphaan setup with one windscherm is nothing you want to take apart the next day. Once you added one or two windscherms, a tent carpet maybe and sleeping stuff. When we take our old Kemphaan to De Waard Winterbeleving, we try to make it a minimum for two nights, three days.
From pure tent construction, the setup of the "two main poles" tents, like a Kapmeeuw or Kleine Burgemeester cannot be beat. The Overlooper is too complex. Our Dwergmeeuw is similar in the main design and it is fast to setup, we expect nothing less from the Kampmeeuw. After some circling.....I really do not understand, why the Kapmeeuw, so easy to build, was taken out of the line....
