Good Afternoon. As i thought, I get better answers here than the usual social media. Anyway, I have the 07 MC 5.9 Cummins SRW with 4.10s. Would prefer better mpg with fuel costs, as I'm sure many would as well. With that being said, upon retirement I am looking into the RV scene. Nothing big like a 5th wheel (would prefer a dually for the 5th), and its just me for now, so prefer a smaller trailer. I do realize I can pull a house with the 4.10s, but also prefer better mpg. And yes, Im aware pulling anything no matter what the gear will lower the mpg.
With that being said, taller axles (3.55, maybe????) may make a difference when not pulling. While i may do a decent amount of traveling towing a camper, I still do a lot of driving without one (not buying the camper till after retirement in December), hence the post. The other option is the GV OD. Not towing, GV will lower the 4.10s to 3.20, which isnt bad, correct? Talking to GV, you cannot tow when using it, so it seems that keeping the 4.10s and adding the GV seems to be the best bet. FWIW, I may have 'answered my own question' and maybe so, but any opinion from those with extensive knowledge with either or would be appreciated. Many thanks in advance, safe travels.
