I just purchased a 26 trd sport AT and plan to tow a small pop up camper GVWR 2900. I will likely be towing it 5-10x/yr with the longest route being down to Monterey from Seattle! I guess I have a few questions,

1. Trailer brake, after market or go to Toyota oem?
2. Distribution hitch, what do y’all recommend/use even if this is under the weight for it I think it will help?
3. Anything I need to be aware of maintenance wise? Oil? Coolant? Breaks?
   3.5. Thoughts on longevity of truck given this?
4. Anything else you recommend

First time Tacoma Owner here and absolutely love her so far. This is the first vehicle that I have bought with Zero miles on her and wondering about two things:

1. Prolube oil additive or similar: is this something that I should think about to help with long term health of the engine (given the turbo) or is this just a ploy?

2. Gas additives like the Lucas additive: again is this something that I should consider to help keep my engine and overall drivetrain happy or waste of money?
