The only problem I run into in very cold temps and long run. Is that the vac hoses can get clogged from the "Snow" that is created in them. It lines the interior edges of the hose and can make several foot long snow plugs. Just part of winter fun. The same as the van driving sideways down the road, you can't stop on ice. hand tools , lines and wands freezing solid because they were on the floor
I have even had the van slide out of driveways while parked on ice a few times. I hate walking out of the house and seeing my van leaving on it's own heading towards parked cars. Fun, Fun ,Fun!!!
