No first hand experience with straight hose vs OEM spec'd formed hose. My instincts would be to replace them with the OEM spec'd hose on your own schedule, vs if a problem did occur somewhere on the road... But, sure could be wrong. Suggest a call to a Cummins Coach Care shop, to ask their opinion.
Hose clamps can need a fine tune tightening after the first few heat/cool down cycles. If it is the proper claiming mechanism, after you reset it, I'd just monitor them as with all holes and clamps. Good chance the clamps will be good to go for quite sometime.
Best of luck to you,
