Kowa Genesis for me have been excellent, very well made and solid to hold. Maven, Zeiss, and Leica have good glass also. Try them as everyone eyes are different.
Another Sig p365x here... although I do have a full size M&P I shoot as well. I shot the M&P, Ruger, Hellcat and Glock side by side and I preferred the Sig. I preferrred the M&P over the Glock as well.
Having shot both the Hellcat and 365x side by side in 9mm I prefer the 365xl. Great gun! Both are good but for me the Sig was more accurate and felt better in my hands. I ended up purchasing the 365x with red dot with no regrets other than why did I not do this sooner.
Hmmm, I have a 2012 F150 5.0 Lariat and have had nothing but good luck with it. It has 86K and is getting better gas mileage now than when it was a 50k. Sorry you had issues with yours, but all I have heard and experienced are good things about the 5.0 and eco-boost engines.
Congratulations, you life is about the change in a big way! It will be fun and difficult, but way worth it. Enjoy the ride as it goes by way to fast, although it may not seem like it at the time, expecially at 3 a.m. You got this!
