for thousands of miles with 3/4 tons with no issues.

Then you might pull it off. In any event it sounds like you have already made your decision so good luck and stay safe.

Food for thought on the larger wheels and tires: It is possible that they may raise the truck up enough to create clearance issues with the top of the pickup bed and the overhang of the fifth wheeler. It may not be apparent on straight and level surfaces, but could be a problem in some situations where the trailer and the truck end up at different angles like the entrances to parking lots, gas stations, etc. Any place that has the potential for the rear end of the trailer to go real high or real low might do it.

Not sayin' you will have a problem, but more urging you to double check that before writing a check.

last question. does the 3450lb rated tires mean the tires at 80 psi support
that weight excluding the truck. payload support ?

ok thanks. On the 5th wheel i want they have flipped the axels so it sits a bit higher and will hopefully help. ill look at my clearance carefully.

There are charts available that show the load rating for tires at various tire pressures. You'll want to get the right chart for your tires to be double sure.

The load rating of the tires includes everything that is on them which includes the truck and payload. At proper pressure, the 3,450# rating (the number you supplied here) is for each tire. Those tires can support 6,900# per axle, if the number you gave us is what is stamped on the tire.

That does not increase the payload or GVWR of your truck, but does pretty much assure that if there is a failure due to overloading, it is much less likely to be the tires.

Here's a pretty good tire pressure chart for you. It looks like your 20" tires need to be at least 90 psi or higher to achieve max rating.

Go Peterbilt or Kenworth with a sleeper cab and forget all this stuff....heck, what's another $100,000 ?? ...... In your off RV time, you can be an OTR freight hauler to pay for your rig. AND the bonus is the HUGE AIR HORN...blow it each morning at 7am in the campground as you crank that puppy up and idle it for an hour or so.....

This has been "rung out"....no minds are going to change. BUT, it was GREAT listening to the "opinions" expressed.

Common sense says: safety first. When we haul these monsters down the road, we take on "responsibility" and we all know, even in the best of circumstances, S*** Happens! SURE, you can tow at 80mph; for how long?
SURE you can push your weight limit past max, for how long? SURE you can take that gasser with no exhaust brake down the mountain and pray brakes do not overheat and there is a "Runaway truck ramp" handy...and on and on. BUT, this is SUPPOSED to FUN...white knuckling is NOT FUN...these are controllable decisions. Make WISE choices and let's set the example for safety first.....

Go out and enjoy 2012....life is short...explore; camp and make new friends.

Ain't that the truth. I have probably made more upgrades to prevent white knuckles than for safety reasons. Living at the edge can be fun but not when towing...

It seems like bell has indeed "rung" which signals the closing of this thread. Thanks to all who contributed to a very lively discussion and exchange of opinions.
