Quite easy to make yourself ...................... the rubber being the expensive bit. I prefer the screen on camper as these type flaps reportedly don't help fuel economy plus with screen problems solved no matter what tow vehicle is being used.
Here's a spring pack off a Tambo camper. I use that as an example as these when built by Keith were basically unbreakable ................ heavy but tough as nails. Have four friends with them that have seen four or five Cape York trips with nothing more than some suspension bushs worn and given the corrugations no avoiding that one. Have found you have to either beef the trailer for the load or cut down the load carried as there is probably not much that will leave you in the proverbial more than a broken trailer in the middle of poo creek as your options are limited many times if not fixable to leaving it where it broke. Recovery costs in some places would probably be cheaper to buy another
I know you probably don't want the wish list added to but a Tregg type hitch would be good as apart from the articulation advantage it takes the shock load of the trailer draw bar ............... again depends how severe the use you require it to handle as there are many campers being sold that are great running to a beach camp site and back but take them of the beaten track and give them 500K of relentless corrugations and they will literally fall apart along the road
