Grey water

Just picked up our T4 Trident, very pleased with it - excellent service from Motorhome Showroom in Warminster if I am allowed a plug.

Most questions were answered by the dealer, but what do people do with grey water before driving home?  Do all campsites have a drab you can drive over. There doesn’t seem to be any means of attaching a drain hose to the drain tap so presumably the tank just drains straight down? If the campsite has no facilities how do you get rid of it in that case?

Thanks

Google for waster water carriers for one answer. A little wheeled container you can put underneath, drain into and cart off to the disposal point. However, they take up precious space, so you probably won't want one in a van conversion. I don't have one. I'd be tempted to suggest finding a drain on a quiet street and dumping it straight in there.

I used to use one of those collapsible buckets on my old van. 

Took up no room at all in the cupboard.  Did mean frequent trips across the site to the grey drain though
