I have a new LWB connect,i have a 500ltr tank in mine with plenty of room to spare i don`t know how you can say it`s the same size as a caddy,height and length it`s bigger.I would still prefer more room,my next van will be the transporter or the traffic.If you have poles poking through into the footwell i don`t know how anyone can say that there van is plenty big enough.
