External Water pump - Joocla V2 Hotap

Hi All,

We love this Joocla, having hot showers anywhere is fantastic. I've been using a Milwakuee Transfer pump to pump water from near by lakes/streams into a 100Litre tub I sit under my van and we draw from this into the Joocla but setting up the Joocla pump is a PITA

I want to mount an external water pump under the van, permanently wired into the van power with some external water fittings.

Can anyone recommend a good 12V water pump that can be fitted under the van (and get filthy!) without issue?

Thanks
