Since you will be towing a travel trailer, which is a static load that does not change weights all of the time, I recommend going with leaf springs, see link. If you have a 2 wheel drive model that is not a Pre-Runner, go with # SSA1 for 2,000 pound capacity or # SSA7 for 3,000 pound capacity.

For a 2 wheel drive Pre-Runner OR a 4 wheel drive model that is not a Pre-Runner, go with # SSA19.

Air springs are great if you will be carrying varying load sizes and types so that you can level the bed accordingly. I have included a link to those systems for you as well.

Another option is to use a weight distribution system on the trailer. This will be a better choice for reducing sag and safely towing a trailer because it distributes the tongue weight rather than just raising the rear suspension of the vehicle back up to level.

For a tongue weight of 450 pounds (you also have to add in the weight of anything loaded behind the rear axle of the tow vehicle to this 450 pounds) I recommend a system rated for 200 to 600 pounds like # RP66540. With this system you will just need to add a properly sized ball like # A-90 for a 2 inch or # 19286 for a 2-5/16 inch.

There isn't a special kit you would have to use to install battery isolator on your 2015 Toyota Tacoma unless it uses a Delco or GM CS alternator (which isn't likely). So you would use the regular kit, #DW08769.

The 7290 that you see is a casting number. It is found on AL-KO hubs that fit #99 spindles. I found that the bearings used are #28580 which would be the inner bearing and #25580 which would be the outer bearing. For the seal use #91030.
