A range of fuses on ebay, just one example here;

Thanks for all the great reply's,
The camper has a dc to dc charger already in it, and the Anderson plug is fused,
I will run some big cable on top of the chassis and a fuse near the second battery.

If you have a DC/DC in the Camper then the feed cable does not need to be very big at all.

What size cable and fuse should I use?

What DC/DC charger do you have?

If it is a 20 amp jobbie then a 30 amp fuse at the 2nd Battery Terminal into 10 AWG cable would be fine.

What about if he wants to solar charge back to aux battery, cable size then should be large enough to suit panel reg out-put and distance etc?

10 AWG will easily handle a couple of hundred watts of Solar Panel

I have a 30 amp dc to dc charger and a 255 watt solar panel.

Go to 8 AWG.

10 will handle the Solar easily but is a bit marginal for the max spec on the Charger as a 30 amp Charger will pull closer to 40 from the supply if it tops out.

Thanks a lot.
