Is it possible to finance a $23K trailer for 180 months?

Had one friend buy a DP financed for 15 or 20 years (forget which) payment $1500 a month. Another friend purchased the exact same unit repoed at auction for $48,000 cash, no payments. I sure would hate to be paying $1500 a month on a 15 yr old unit. Mine cost $234,000 new and is now worth maybe $35,000 but I paid cash for it 20 years ago and its old but good as new, I am old to!
