I drove for my camper to north Michigan from San Francisco, so the "long drive" is subject to personal perception. That was in -20F winter BTW.
Yes the Generac is build-in and it takes 2 compartment.
2nd is for huge inverter box with 2 huge fans on the sides, but the compartment has no ventilation.
I guess I never figure why anybody in his good mind would put such propane-guzzling, breaking twice a season, extremely expensive ornament in camper, where space and weight is at high premium.
Once I build front rack for Honda, not only I will have reliable, cheap, fuel saving and easy to replace unit, but my Center of Gravity will take whole meaning.
Now I might put my spare wheel back under the truck.
I used that Honda in my bus years ago and one fill up (2.4 gal) was running 15k AC for solid 12 hr.
