What brand of RV are you looking at? It is extremely rare for a 40' motorhome of any price range to have the IXB-6.7 engine in it. A lot of them have the 360hp ISC engine in them that has 950 ft-lb of torque. Unless you are bothered by the slower hill climbing ability of this combination, in my opinion it would be more than adequate to meet your needs.

I'm not so sure you're accurate. I think you meant ISB 6.7. Many motorhomes are (were) equipped with the ISB 6.7. 0ur 2013 Fleetwood Expedition has it in it - 360 hspwr & 800 lb-ft torque. It's almost 42' long. I believe the Discovery (2013) got the ISC 6.9 - 380 hspwr - 1200 lb-ft torque.
We've had no issues pulling a 4600 lb Jeep Liberty. It's rated to pull 10,000 lbs, I believe it will.
The Discovery is an ISC 8.3 in 2013. Biggest difference between the two (ISB vs ISC) is going to be MPGs. I get about 7.8 - 8.3 where the ISB will probably see 8-9 or higher. I have driven both and don't see much difference. There is a lot of difference in the 6.7s that are 340HP with the Allison 2500, they are not enough for 30K+ lbs, IMO.
