Dave, with your requirements of being able to carry a 9' camper and a 16' open boat you really don't need the expense and hassle of a diesel engine. If this is going to be your primary mode of transport; look at how often you will be putting it under load, and just how long you intend to keep the vehicle. The breakeven point on a diesel vs gas is nearly 200,000 miles. Dodge's new hemi gas engine will meet your needs. However if you do intend to get a 13' camper and a 24' boat then by all means get a diesel.
