As far as I know, there isn't a specific manual on the V-Cross. Mine came with a generic manual that pretty much provides general information. The individual manufactures manual on the appliances were also included. You should be able to find those manuals on the individual manufactures web sites.
We have the 275VRLF which is smaller and we upgraded from a pop-up. We are happy with the trailer after we made a number of changes to tailor it to our needs.
If you have specific questions, I will provide any info I have.
Hope you enjoy you rig as much as we have enjoyed ours.
