I was lucky. I had many 2x2’ cement pavers about 2” from a local source. I lined them up, leveled them (mostly) as two tracks for my TT. Yes, they still sink in some under TT’s tires in storage but they helped a lot. My yard soft spot was the ideal TT parking spot and not much larger.
I agree with the bite the bullet crowd. Paving is the best way to go, long term. Depends on your future housing plan for cost effectiveness but a level paved surface is a selling point for future garage additions, patio, entertainment, lots of possibilities.
