Just Differentials Ford F450 4x4 Motorhome on 42's Build Thread

[nitro-gear]

Our new Goodyear tires showed up and we got them installed just in time for Overland Rally! So far we have noticed these tires are much quieter than what we had on here before. We look forward to putting lots of miles on them over the next few years. Come stop by our booth and check out the F450 Motorhome this weekend.

I have the same tires on my rig, and so far they seem far superior to continental MPT81s. Quieter, and the compound in the tire seems to wear better. They are still massive tires and come with the attendant balancing issues etc. but I like them much better so far.

What tire/rim/adapter combo are you using now?

You will love those tires. Like S2DM said they are large tires and come with their balancing issues but are quiet and handle great off and on road. We love ours.

A couple more pics of the F450 with the new Goodyear tires installed. They spin very smoothly and are much quieter, we can hardly hear them over the wind noise in the RV. These tires run a big larger than the same sized continentals and are about 2 inches wider.

Do they handle the same as the large Conti's?

They handle much nicer than the continentals, and much quieter. Not sure on wear yet, too soon to tell

Somewhere along the way of this build, some of the stuff that we have done hasn't been updated. Last year we decided that the 6.0L Ford diesel wasn't what we wanted, no matter how we built it. After some research we decided to bring the camper to Diesel Conversion Specialists in Kalispell Montana so they could install a 6.7L Cummins. With the help of a ATS built 5R110 Torq-Shift Auto Trans (with a high capacity ATS aluminum trans pan) and a Five Star Torque Converter (built for the Cummins/5R110 swap) the crew at Diesel Conversion Specialists were able to shoehorn in a twin turbo 6.7L. Our Ford has become a Fummins!

Here is a current spec list on the rig:


-Suspension: 2005+ coil sprung F550 Frontend "fatboy" Dana Super 60 swapped in for better ride, wider track, tighter turning radius.

The camper gets plenty of use year round. It works great for ski and snowboard trips during the winter!

If you live on the Central California coast you might have spotted the Nitro Expedition RV making some rounds as Carl was in the area to visit some Nitro Gear and Axle dealers and see some family. The rig also got some dirt under the wheels (and some air) doing some trail riding on the way to a remote outdoor punk rock concert in the hills outside of San Luis Obispo. As luck would have it Nitro dealer and owner of Poly Performance, Dave Schlossberg, was headed to the Pozo Picnic also and suggested an alternate route to the event on High Mountain Road. This dirt track/4×4 trail would end at the Pozo Saloon and make for a perfect way to take the road less traveled. Rolling out about 11am the mountain road started out as a typical mild dirt road, but with some very tight spots when you are in a 17,000lbs RV on 41″ military tires. Overhead clearance was an issue as the trees in the area weren’t really trimmed enough for the extended height. A few branches came down, but no damage was done to the big 4WD Ford.

The last 1/4 of the trail got interesting as washed out rutted sections of roadway left trenches deep enough to twist the suspension to the point tires were being lifted on occasion and the traction adding differentials were getting a workout. Carl noted “It’s a weird feeling lifting wheels on such a big rig, but with the twin turbo Cummins and oversized axles we had plenty of power and confidence that everything would hold together. After about 4 hours offroad cold beer waited for us at the saloon and the concert ended up being a blast.”
