Rear mounted locked container for my motorhome

[Penzance Stag]

Can anyone point me in the right direction to get the right container ( mounted on my bike rack ) to enable me to put my spare wheel & tools in .
Hoping then it will free up room in my Benimar for internal storage

Fiamma do one but you need to Check your rear axle loading.

Fiamma Ultra-Box 500 Rear Storage Box

wouldn't recommend putting a spare wheel on a bike rack, to heavy.

I'm too scared to use my bike rack any more after seeing a picture of a cracked back panel on an identical van from a dealer fitted rack.
Will get rid and use a tow bar mounted one.
