I agree with you about small caravan type doors. My doors just take up to much space with the swing hinge and I want to reduce the size of the step hole in the floor. A 30 inch wide door is what I want, easy enough to get stuff in and out and more floor area. I like your remote lights very handy, and your spare wheel carrier I will have to do something similar as no spare came with it.The big doors are handy if moving goods for home or van,my electric door was shot to as the a-s h-le before me got at the relays and wiring,i removed all the motors and its so easy to open and close by hand,small trailer tail gate bolt is used to lock from inside,small thin doors are a pain in the butt.
I also fitted all lights with a over ride remote on key fob which i now have control of under step and step internal light for arriving back elephants drunk at night.
