That is the exact kit that we have. Depending on placement, you may want to consider adding a few extra feet of cabling and Y connectors, as well as fuses. We tried to build ours for future expansion. Our coach did not come pre-wired, so we made our own cable pathway to the battery compartment.

Just a note - the controller in that package will handle the 400W (30A) of panels but you can't add a 5th panel (or more) in parallel without changing the controller to handle the additional amps that are to be generated.

Lastly, you will want to get your roof diagram from Thor so you can figure out where the roof studs are and drill into them for better holding power. Use plenty of Dicor and/or Eternabond tape to seal it up good. I used Dicor to put some "spot adhesive" on the cabling along the route to hold it in place.

400W isn't a lot of solar power, you will need more to keep your 2 batteries fully charged. Of course, a lot depends on how you use the battery power that you have. We generally run the genny an hour or 2 in the morning and then before bed to top off the batteries as we are energy hungry technology people always watching TV or playing Xbox, as well as charging laptops and phones and powering our 2 MiFi access points.
