weve just brought one for our Trigano,, it arrives tomorrow and will be trying it out next weekend,, if you can wait that long,, i will let you know how it goes :)
We have one that we used on our Trigano trailer tent last summer and it worked really well, even coped with hurricane bertha with no leaks. The two eldest slept in it with no complaints.
We have a Pennine pathfinder this year so have yet to try it, but I have seen photos of them with a pathfinder and they look to work just as well.
