I have a 25 litre tank under my cupboards. It's long and quite thin with wheels on one end. There is access through a cupboard and as the pump screws in I can take it out for filling and cleaning. Does that help?
i have a 75ltr clean water and 31ltrwaste water tank under my t4 from cak and very pleased with them.clean water is filled up from a lockable filler under the bonnet.i found them a very good firm to deal with although they get very busy they took the time to talk me through a couple of things i wasnt sure of
We manage to get away with a 10 litre water container for most weekends with another wedged under the van to collect the waste water. I ditched the 25 litre container that i originally fitted to save space. I suppose it depends if you're wild camping & drinking lots of tea & coffee, or using campsites & drinking beer I:
I too fitted an under floor tank from CAK tanks - excellent firm - they also repaired mine for me after I damaged it going too fast through some deep water - had to fit a waste water tank size I think 35 litres because mines a Caravelle which has a second heater underneath where the tank would normally go - mine fits underneath the sliding door - seems big enough for normal use - drinks, cooking etc for about 4 days.
Best to use black tubing which doesnt admit light so less growth of nasties - CAK also do a sterilising stuff to clean out the tank at the end of the season. I didnt want to drill large hole in side of van for filler so routed some hose through to engine bay and mounted filler on a plate above the rad
