Hi Mark,
I own a fjellheimen camp2.
It's a lot of tent for not too much weight.
Similar to the nallo 2gt.
Plenty of room for two people, a vestibule that is big enough to store two peoples gear and still have space to cook for example.
There is however still room for improvement,
when wet the tent stretches quite a bit, making the shape at the backside of the tent such that it rather catches the water instead of shaking/loosing it. (hard to explain, i have pictures somewhere showing what I mean, if you want to see)
Also I need to use the seamsealer now at several seems. Last time I used it, it leaked trough when it rained for a whole night and morning. The innertent however kept everything out.
But that said it has withstand all sorts of weather, even some unexpected snow in Patagonia.
(tent is now approx. 2 years old)
hope that helps,
Gregor
