What is the opinion that tires could wear a bit unevenly if the camper is not exactly centered, off by maybe and inch to one side. My passenger tires are wearing differently on the outside compared to the driver side. The camper currently sits more to the driver side. Thanks

Opinion, it does not matter in the big picture if the camper is not centered and off a inch to on side. Most campers are heavier toward the drivers side, or where the heavy kitchen and other stuff is located. Your gas tank has weight and changes when you are empty verses full tank.

If you wanted to be accurate one could weigh load at each tire empty and loaded and adjust a tire pressure for average weight for each tire. Most are not going to do this. So watch your air pressures and if you know the drivers rear tire has the most weight could add a couple of psi more, or so.

But you say the tire is wearing on the outside, under inflated will have wear in the outter both treads the while over inflated tires will have wear on the center tread surface. If you have just wear on the outer tread. Then it might be time to check inflation and have a alignment to see if you are in specifications.

Ditto on the alignment issue.

On my 2002 Tundra /ATC Bobcat with 265/75 16 tires I run #45 rear #40 front.

I also watch the center of the tread mostly.

If over inflated that's where they will wear the most.

When was the last time you rotated your tires?

In the state of Oregon, roadside weigh scales remain "on" 24/7 and the motoring public may use them.

 

It is very easy to weigh each wheel by choosing how you drive onto the scale.

 

I once did this with a commercial load for every axle and separate wheel....took a while.

 

Should a commercial vehicle enter the scale while you are weighing, courtesy dictates that you let them weigh  thru and then finish your measurements after they are gone.

I rotate about every 6500-7000. The truck only has 13,000 right now. After closer time inspection the wear probably isn’t to excessive. I might be a bit jumpy after pricing a set of new ones out of curiosity. Time to budget that!

If your spare has the same showy rim and the same tire ( i buy 5 at a time) you can do a 5 wheel rotation.

What kind of truck do you own and does it have a live/solid axles or independent?  I was going to say that uneven tire wear is unrelated to the camper, that it is due to alignment/suspension.  The argument could be made that the camper impacts that though.  You would only see that with independent suspension though, and only under the most extreme cases.  An inch to one side or the other will have no discernable impact.  Your uneven tire wear is not related to where the camper sits on your truck.

 

ETA:  Looks like you have a Ram 2500 with solid axles front and rear.  Your front tire(s) is probably turned inward, the toe needs to be adjusted.  I've seen this on Dodge trucks in the past.  You might take your truck to a shop to have the alignment checked.  Wear on the inside/outside is a toe issue and should be easily correctable.  Suspension has a lot of parts associated with it.  Not really difficult to understand, but a number of variables.  Without getting into the moving parts, you can get a good understanding of caster, camber, toe-in, etc and then understand tire wear or odd handling, especially over varied terrain.  It's kind of a fun part of the mechanics of vehicles.

If your camper is really only off-center by an inch I strongly doubt that is the cause of your uneven tire wear. Few trucks are balanced side to side from the factory, and even filling the fuel tank will throw that off anyway. Much more likely it is an alignment or shock issue.
