That Ford V10 is a beast. It will do what you are asking of it.
It's going to be more noisy while doing it, and might not get as good of gas mileage. Definitely wont outlive the diesel, but they still build them to go 250k+ miles
I had a similar question recently, and after much investigation I concluded that it's better to buy a higher end gasser than a lower end DP in my opinion.
Couple of things to look at more importantly with the gasser are how well it's built. What sort of roof it has on it, and that the wheel base ratio is.
The shorter the wheel base it has on it the more it's going to want to wander and if it has a long tail on it the tow will pull at you.
If you can find something with a long wheel base and possibly factor in some shock upgrades you'll also be able to solve the problem of not driving as well as the DP.
