I have 2000 eagle and you can tow a big boat no problem. I tow one down to the keys every year.
The problem is when you launch with a diesel pusher down a ramp and step on the brake what happens. The weight of the engine pulls up on the front wheel reducing the braking power and the rear wheel slips on slime and oh sh&^% splash!
I had a gas rig and lauched it easily, but when I get the to the keys with my eagle, I going ask someone with a truck if they want to make a quick 20 bucks.
I would recommend a gas rig or a front engine deisel if you need to lauch. Today I just goy done replacing the fuel lift pump in and 350 hp cummins ISC. If you looking at the dream, check ex manifold, radiator, inverter and ball joint boots. I bought mine 1 year ago and sank 10k, plus 4k for tires and still need to pay 3k for new ball joints because the boot are prone to deteriation.
We enjoy the complement and the looks of the eagle. Put miss our hurricane that was paid for, didn't have air bags, valves, hydraulic motors and pumps, air compressor, and norcold fridge that known for starting fires.
Let me know if you have questions. good luck
