Eribas look as if they have a massive payload, however the quoted weights are for a fairly basically specced van and when you start adding in the options and extras the payload can rapidly disappear. I built the attached spreadsheet in order to make sure I'm running with the allowable limits. You'll note that it's set up for my current van for a particular recent trip, but it's an easy task to add in your own van's weights and your own load.

I also included the car so that I could check I wasn't overloading it and to automatically calculate things like Train Weight and BHP/Ton (40 being the recommended minimum).

Feel free to amend and adjust as you wish.

Excellent - many thanks.
