I'm not in the market and probably wouldn't be for 20-30 years if ever but side radiator(s) would be a must. I have to be able to fix something if need be, I am my first line of defense in finding something wrong and preventing it from getting worse/more $$. Right angle gear boxes, if properly maintained, can easily outlast the engine @ 20K+ running hours. The power defict between a direct belt drive and a bevel gearbox drive would be very low, on the order of 3hp or less difference given the speeds these engines run at. I used to work on class 8 trucks so I may be a bit biased but if I owned a DP coach, I would first be prepared to pay whatever was required to maintain it before buying and then taking it to the dealer for as little as possible for as long as I was able/comfortable taking care of it myself. I hate with a passion systems that are poorly packaged thus making maintenance and repair unnecessarily complicated and expensive for those dependent on dealers for service.
