I will throw my 2 cents into this thread. I have driven over 90K miles on my ISB equipped Discovery loaded to 32K lbs with a 5K Jeep Grand Cherokee toad. There is no mountain in this country that I could not top. I can run 70 mph all day long pass semis up mountains with ease. Sure I have driven an ISL equipped Revolution, and yes it has slightly more power, but nothing crazy. I travel in tandem with my buddy in his Revo with the ISL. I have absolutely no problem keeping up with him. These are not meant to be race cars. They are just designed to get you from A to B. Almost all motorhomes gas or diesel will get you where you want to go. I would worry less about the size of the engine than the features that you are looking for. There are thousands of Discovery's, Phaetons, and Ventanas out there with ISBs that run all over this beautiful country without any problems getting up all the big hills west to east.
