USMC,
To answer your questions...
- This is my first season with this setup. The guy I bought it from ran the exact same Tundra setup with bags and E tires for 3 years and said his experience was great as well. He did a lot of highway and mountainous terrain out west.
- Just completed a 300 mile trip and the rig was an absolute dream. I had the Lance 825 and my Skeeter bass boat that added a couple hundred more pounds of tongue weight. The Tundra got 10 mpg.
- Braking is fine, but I'm sure it's further than without a load. I have the transmission help with slowing whenever possible.
- Fridge is small and I ended up shuttling a lot of beers from warm storage to fridge. Bringing a cooler next time!
