Mountain huts in Troll peninsula

Hello,

We are a group of 6 friends coming over the Troll peninsula for some touring ski this month of March.

We wonder if there are mountain huts available to sleep, that can be used without the need of contracting a tour with a private agency. Just as we do in the Pyrennees and in the Alps, a place to sleep where we either pay a fee or either it is open for public use for free.

I would appreciate any information, even if negative. The reason is that our luggage needs to be adapted to the possibilities of accomodation.

Thanks a lot!
