New Owner with Old Questions: Cap, Seat Riser+ Flashing

Hey Guys,

I did a search, and couldn't find what I was looking for. And I figured I would ask local people due to our particular market, exchange rate, and weather.
Truck is a '23 black base OR/SB
Truck caps: looking for a hard shell cap. Does not need top racks. On the fence about "windoors". Don't need a front sliding window. Needs to be lockable. Main use would be for securely hauling camping/hunting gear. Anyone have any recommendations around the Golden Horseshoe area of Ontario? I went to action a couple of weeks ago, and they quoted around $3000, 4-6 week wait for their branded cap...
Seat risers? Worth the money? 5'10, and I'm already hitting the steering wheel getting in. Anyone local to Hamilton that has them installed that would let me try (just sit, not drive) them out.
Flashing: how long should I wait before I flash the car? (goes out to driveway and lifts shirt at truck). The truck has about 550kms, so it's not even broken in yet. Yotatune (think that's right) is doing them in Burlington in the near future.

TIA for any and all help.

These guys are in ST. Catherine’s and I’ve heard good things.

I tuned my truck right at 2k Km. Just hit 100k and not an issue. Yotatune are awesome dudes.

I’m 6 1 and haven’t ever felt the need for seat risers, but I’m sure someone’s got them.

 

I'm 6'0 and I like the stock seat position as-is. You can always try it out by loosening the two front seat bracket bolts and shoving some 1" thick material (like a piece of wood) between the seat bracket and the floor to simulate a seat riser.

You can flash a tune at any time and still observe the break-in period precautions as described in the owner's manual.

 

I think so. I'm the same height and have them installed in Hamilton. You're welcome to try them out. Or come out to the trucks and coffee next weekend
