A Fjellpulken fiberglass sled costs nearly 1000 €, but you can get a sled much cheaper than that. EraPro Paris Expedition is a plastic sled which works well for some purposes, and you can buy one for under 60 €. You can find them for example at Varuste.net. In Sarek, I pulled around one, with Fjellpulkens parallel drag, and it was perhaps not the most optimal in mountain conditions. For glacier skiing it should be perfect, because you mainly ski on a flat surface. I got an own Paris sled which I have equipped with rope drag. I have drilled some holes in the sled, and attached a rubber band for holding the load in the sled. To get the luggage in shelter, I have a big bag that is as long and wide as the sled (Snowsled Expedition Bag). As harness I use the basic Fjellpulken harness, which I have equipped with a chest strap.
Arctic expeditions often uses tunnel tents, because the shape can handle the wind and the tents are easy to roll up into a large roll that is attached on the sled. Today i attached straps on my sled, which can be used just for this purpose. The straps also keeps the stuff in the sled steadier in place. Bauhaus had 25 mm straps and fitting clips for the purpose.
