A 205/75-15 tire is what I'd recommend. The tire would be 1 inch taller in diameter which would raise the ride height by 1/2 inch, and the tire would be about the same width as your existing tire, which is 8 inches. .
If a Load Range D tire with a 2150 lb per tire/4300 lb per axle capacity would work for you, I'd recommend the Taskmaster Provider tire, part # TR20515D.

The # K71-359-00 is most likely the best choice to go with since it's a very universal and also well made design but it really depends on the equalizer size you have now. This one measures 5-3/4 inches from left to right hole centers and then is 2 inches tall. This is a very common design so I'd be surprised if you needed something else but you should check to be sure. view full answer...
Yes, you can use leveling blocks to support your stabilizer jacks, I recommend the Ultra-Fab Leveling Blocks for Trailers and RVs - 8-1/4" Wide x 8-1/4" Long - Qty 10 # UF48-979051.
Not knowing the weight rating of the A frame jack I can not say yes or no. You will have to find out the weight capacity and tolerance of the specific jack. view full answer...
We can help. We have the Global Link Ultra E Pro Electronic Lock for Travel Trailer w Keyed Alike Option, # 295-000183. This fits into the same cut out as most travel trailer locks, which is approximately 3-3/4" tall x 2-3/4" wide. The dual locks let you lock only the exterior handle, or both the exterior handle and keypad while the interior handle remains unlocked for emergency exit. The Lithium battery is included and this has ability to be keyed alike to match other Global Link locks.

Yes the width of the crossmember on the Ultra-Fab Power Twin II Electric Stabilizer with Dual Motors - 30" Lift - 6,000 lbs # UF39-941705 will give you more surface contact on the frame of your 2015 Keystone Passport Ultra Lite Travel Trailer. This will reduce some stress by spreading the weight of the trailer out more.
To keep this upgrade to your Passport Ultra Lite as light as possible I recommend the Lippert High-Speed Power Stabilizer Jack - White Switch Kit - 30" Lift # LC369774.... view full answer...
The Dometic 300 Weekender RV Toilet part # DOM64FR that you referenced does come with a base seal so you would not need to provide that separately. No additional components are needed to install this. view full answer...
The Equa-Flex Cushioned Equalizers part # LC314336 will work with any standard 9/16" should bolt. The Lippert Components Tandem Axle Equa-Flex AP Kit part # LC64FR would be a great option to use since it uses wet bolts and comes with shackle straps as well.
