astro85 very valid question.the only chance mfg.piece was years ago it was the olympic bobs.clone to a bayern kurve,i guess maybe those european builders had a jump on us builders,of those huge pieces.when they started hitting our shores.they pretty much had the ex.on them a lot pieces would hit those parks on east coast.be showcased and sold at least thats how i remember it.maybe kind of hard to duplicate.the flying bobs.and those chance pieces came close i would say.but look at a true mack matterhorn,or mack himalaya.always looked good.really cant answear your quuestion.economic,s maybe.and currency exchange at time of purchase.now a days its less loads for shows,but some do carry multi trailer pieces,some one stated here a while back the patron can not tell the diffrence.long winded in summary i really dont know.but I'm sure somebody here will answear to your question better then me.ok then bigjlh
