The tires we have seem to have reasonable reviews, they're Sailun S637 G rated and appear to be much more heavy duty than most. We also already have the correct track system, auto adjusting brakes, 7k axles, and the shock mounts look to be secure enough. The spring packs look a little on the light side as I recall and I don't remember having a wet bolt setup so I'm adding those to the TO Do list. I had room to keep my old TT at the house but now have to store the new setup in a storage lot until I get a pad poured in the spring so I can't verify things easily. Of course in the storage lot there isn't room to put the slides out.
You guys pretty much have me sold on the Solar, and I'll probably go with 4 6vdc batteries, I just need to find a battery box that I like to go up front. I already have a 400 watt pure sine inverter, and will probably go with a configuration where I can use that, and maybe a larger whole house 2000 watt system if desired. The dual system to keep parasitic drain down makes sense to me. Now I need to get into the electrical panel and see how it's wired, and how much trouble it will be to isolate the desired circuits through transfer switches, and maybe sub panels.
