Tundra RV Towing Capacity

Hello, my husband and I have a 26ft conventional trailer with a GVWR of 7,500lbs and a tongue weight of 618lbs.

We are looking for a truck to tow our camper as full time campers, so it would need to be capable of towing and stoping on mountains, hills, turns… Anything we might come across.

We have been looking at Sierra and Silverado 2500s and F250s but have recently heard the newer Toyota Tundras have good towing as well.

So just looking for advice on whether or not you think the Tundra would be a good call to look into or if we should just keep looking at 2500s and 250s. Thank you!
