Should I keep or sell?

I bought this 2011 Tundra crewmax 5.7 4x4 with 223k miles off Facebook for only $6,800. The guy originally posted it for $7,900 but we talked him down due to odometer rollback. I've done over 4 vin searches and there is no theft record, last spot that had it was auction. So far I've replaced valve cover gasket with oem, oil and rear diff service, coolant service and have been monitoring and fixing what little things come up. Shifts well and engine is strong. But it has cam tower leak, and hood and cab are in need of paint. Should I keep?
