1st off Hello, newbie here. Looking at 2 Sundancer 340's, 1 has only 80 hours and is exceptionally clean but has 6.2L engines, other has 210 hours, clean as well but has 8.1L engines. Any pros and cons appreciated. Difference in cruise speed, fuel economy ( if there were such a thing ) and bigger concern resale value down the road. Thanks for reading and all comments appreciated.
