Hi Harry. It depends on how many bad hats you intend taking 
Seriously though, many folk always make fun of us for the amount of "stuff" we carry and yet we have a 1000 Troll which we've owned for 10 years. Also consider that we are used to going on three month adventures so we always take more than the normal amount of "stuff".
It's fair to say that most of our stuff is carried in the tow car as with any Eriba, it makes sense to do so if you possibly can.There's precious little sitting/sleeping space in an Eriba anyway so the tow car is very useful to stow all those extra bits and pieces.
