Underslung LPG tank on a Adria Coachbuilt?

[Mr and Mrs O]

Hi all
We have paid a deposit on our first Motorhome and look forward to using it all seasons
My question is ro free up locker space is it a good idea to go with an underslung tank or just go with gas low bottles. I think that the cost is going to be about the same?
Thanks

Underslung every time. Free up locker space. External filling point. Weight lower down. What’s not to like?

the extra locker space is only a benefit if you have spare weight capacity
