Okay so I have created a list of nice to haves and need to haves. I live in Ontario Canada where extended patches of cold weather are a reality. I know the AS on the LTD and LHorn were upgraded for Gen 5 and Although I really, really would like to have AS this is ultimately an option I can pass on. Reason why is that I read, on this forum, that the coils actually ride smoother when factoring in the same 22 inch wheels, temps and approximate tire pressure so right off the bat is that correct (are coils smoother than AS)? Next up is all the radar guided cruise and tech stuff...I think this is the entire Level 1 group along with the HarKar audio system. So to me this falls under nice to have but, ultimately as long as I have a front camera an back up camera (so that I don't smash this monster when parking...former Audi owner so to me these things are HUGE) so just wondering whether any of you would say "No, no man...you absolutely gotta order Level 1 and here's why...." so appreciate the feedback here. So next up is the Panoramic sunroof and I will be honest I don't know that I could live without one. I know they leak and the leaks sometimes lead to the casing on the rear sliding window cracking but I use sunroofs all the time...lubricate and clean them semi-annually and have never ever had one leak or fail...and again I use these things daily in the summer. HOWEVER and this is a big however, my main motivation for buying a gigantic truck is space and quite....so can anyone here confirm to me that a LTD or LHorn without the panoramic sunroof is a) bigger for headroom and d) quieter than models equipped with the panoramic sunroof since doing so would make me pass on the roof...even though I think I'd have buyers rumors that very afternoon. Rambox and MF tailgate are easy for me to decide: answer is no. With the cost savings of not going crazy with these options I was thinking of a ceramic coating (by the way if you think I know nothing about trucks...my knowledge of these coatings is even less) and rust proofing (again live in Ontario where its cold, snowy and really salty on our roads so think that would be good idea?). Oh shoot almost forgot: trailer brake gain control...so I don't have a massive trailer and probably won't ever have one but does NOT getting trailer brake gain control mean the truck does ALL of the stopping whenever a trailer is hooked up behind you? That's probably not an issue if you're towing 3-4K pounds but I guess you'd really need it in the 8-9k pound range eh? Okay sorry that was a lot but again I don't really know a lot about this stuff...
