You are better off doing it yourself and with the savings you can get upgrades to your system. Additionally, you will know it was done correctly. Don't expect the factory to wire the system to ensure less than 3% voltage drop (less is better).
When discussing solar, you need to have an idea of what you want it to do for you. I have a side job of installing solar on RVs and I do about 3-4 installs a summer. I cannot tell you how many people want solar but can't tell me what their expectations are. Many want solar to run their air conditioner and that is doable for usually not economically feasible.
If your idea of camping is going to a campground with hookup power and other amenities then solar is not cost effective.
If you are a dedicated boondocker then an energy audit is something you should consider doing. For most folks, a 400 watt, 440 amp hour (4 go,f cart batteries), 1500 watt inverter (or smaller if you don't want to be able to use your microwave or high power items for short periods of time without running teh generator) with a MPPT controller is sufficient.
Congrats on our Wildcat. We have a 9 year old Wildcat and love it!
Do a search on "12 volt side of life" to understand that some items are powered by 12 volts DC on your camper and some are 120 volts AC, and some require both 12 volts AC and 120 volts DC to work properly.
