161 Octane measure?

Any one have a 161 Octane that can measure the cargo area?

I need the actual rear door to refer cab measurement and the front of the refer cab to the wall of the entry, then the actual interior measurement form the fold up couch to the fold up couch.

Trying to see if this will fit my motorcycle with a side car. I think it will but it's all with in 6" here and there.
