Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
Yes, trucks with four rear tires generally have more payload and max towing capacity. However those numbers are set by the vehicle manufacturer. Tires are not the only factor.

I looked at 4wheelonline, it's a truck parts supplier. My I ask a question? Is the OP trying to change a SRW truck to a DRW by just changing the wheels? If so, then the towing capacity is unchanged. I think the OP is trying to "create" a dually by changing out the rear wheels. If I am mistaken, I apologize, but I know the answer the LarryW21 provided is assuming you are changing the truck, not just the rear wheels.

Yes, dually wheels help in increase the towing capacity of an RV. There are a couple specific weights to be aware of. The rear axle weight rating of the truck and its combined gross weight limits. I suggest you read up on both.
I'm going to reiterate what Ron and Larry said. Just adding tires and wheels (converting from single rear wheels to duals) will do nothing to increase your "legal" towing capacities. In fact, they can lead to problems. I remember a case of a vehicle that had been converted and a slight imperfection cause it to sheer the lug bolts on one side of the axle and both wheels coming off.

This question falls into the category of people buying undersized vehicles then believing that by adding components i.e. dual wheels, air bags, springs, etc they can build their vehicle to match a equivalent factory unit. Unless you can get the vehicle re-certified to increase the original manufactured specs, the vehicle stays at the original. While you may believe in your “peace of mind” upgrades have accomplished the goal, there is a legal consideration still there. In the unfortunate event something should occur, a decent attorney could go after you for creating an unsafe situation.
Bottom line in my opinion is there is a reason for the door stickers. Use them, don’t scrimp with a “good enough” attitude, and it’s better to have too much then just enough or not enough.
