I am considering whether to buy a Fleetwood Bounder diesel or Discovery. The Bounder is 5.9l 300h.p. while the Discovery is 7.2l 330h.p. I have not been able to find the torque & manf's specs on these two engines thus far. I intend to pull a medium sized SUV or my m/c trailer with my 2 Harleys. Is there really that much noticable difference in these engines' (pulling) power ? Also, any opinions on any differences in amenities and quality between these two models. :question: Thanks.
