using a veneer for covering plywood construction

Hello,
My steel tube frame is now complete and rolling. Originally I planned to cover my 5 x 9 trailer body with FRP, but then I saw images of the Wyoming Woody with its aniline dyed plywood exterior that was covered with three thin coats of clear epoxy, then covered with urethane spar varnish for UV protection. Few things cause such a response in me as finely finished wood.
With the UV problem here at 6,500 feet, the Wyoming Woody's solution seems practical here along with the added aspect of a beautiful appearing camper trailer.
The problem is in dimensions. I ceased seeking 5 x 10 plywood for the sides in New Mexico and will be joining two 5 x 5 Baltic Birch sheets for the sides. Then other problems popped up: There is a seam and also birch plywood simply does not take a stain evenly and the result is blotches. I have contacted a veneer company for an Oak 5 x 10 veneers for each side. I figure I can match the veneers on the sides by using oak veneered plywood for the top, which can be standard 4 x 8 plywood.
The veneer folks seemed to think this application was doable, but the epoxy used to apply the veneer would be all important.
So, I am reaching out on this site hoping to locate someone with experience in applying veneers to plywood for external usage. It would seem that all the money I have saved for various camper components in buying a used popup camper may well be spent on purchasing two large veneers, but that is my choice. Someone on this site must surely have applied a veneer application to the sides of a trailer larger than 4 x8.
I thank everyone who was kind enough to share with me their wisdom in the frame questions I submitted to this forum. Their direct ideas and helpful attitude resulted in features that made my frame much more user friendly. Thanks so much!
