I'm a proud owner of a new 2 me, 2010 RT-622 Roadster trailer. I love the look and features of this trailer. Have some new bee questions.

I've been browsing some of the other post here and see the part numbers of the bearings and seals.
Where is the best place to purchase the hub assembly online?
Where is the best place to purchase just the bearing and seals? And can you get it in a kit instead of ordering individual parts?
For a replacement hub, will this work? https://www.northerntool.com/shop/to...390_200442390? It says it is a highspeed hub 4/4 on 1 inch spindle.

From what i see my tires are the original tires manufactured in 2010, I plan on replacing them. What tires do you run? What is the speed rating? Where is a good place to purchase them?

The front plastic stone guard has a 2 inch cut into the plastic, Where is the best place to get one of these? Is it easy to change?
Anyone experiment with using Wraps? or truck bed armor like line-x, Herculiner, or Duplicolor Bed liner to help protect the lower front? Love to see pics.
What about a tail guard (for rear pan) as it looks like it has been dragging the ground some. Some sort of chrome wrap around glue on (or screw on) panel cover that could be replaced would protect that painted section from dragging.. just a thought...

The trailer had been repainted and the previous owner had removed the carpet. After reinstalling the carpet, the carpet won't stay up, needs new velcro type pads to hold the edges up, what is the best thing you've found to hold the carpet edges up? Can replacement carpet be purchased?

The two lids are not quite matching as far as fitment goes, the rear lid is 1/4 inch higher than the front, is there any adjustment on these?

Trailer towing arms rises a couple of inches higher than I need when the trailer is level, does anyone make replacement arms (tube) that are more straighter, less of a bend, than stock? Just curious, if anyone has these already with different rise height in the bar. I know i can get different receiver adapters to adjust the height, but curious otherwise if anyone has just replaced the tube.

I have the Owners Manual, but anyone know where i can just find just the shop repair manual for the RT622 trailer?

Thanks for your time in advance for your advice.
