We use a 14' aluminum open trailer for three short-track sleds. We like the trailer, it has a big salt shield on it, but we don't like all the salt and road grime getting on the sleds, event with covers on the sleds. Are there decent options to covering the trailer or at least the sleds to keep them clean while traveling? The trailer is a 1998, so we wouldn't want to dump much money into it. Ultimately it would be great if the trailer also served as storage for the sleds when we are not on trips but for now the main concern is keeping the road grime and salt off them when traveling. It's incredible the wear and tear they get on them from trailering compared to sleds that never see an open trailer.
