Oh my stars Wendy, you've opened a can of worms! You are going to get lots of opinions... and I have mine
I've owed the BAL leveler for years. Used it a LOT with my Scamp
. I'm a single traveler, no one to help me with backing onto blocks (or pulling forward). I just picked the spot I wanted (where's the door?), unhooked and used the BAL to level side to side. NIRVANA.
Now I have a tandem axle
trailer. Same situation... single, don't want to haul a bunch of stuff. Now I have TWO BAL levelers. Still works as needed and I couldn't be happier.
Folks will say they're heavy and greasy. Heavy is subjective and if the BAL levelers are greasy... something is wrong.
Your choice. Whatever you come up with and decide, I hope it works for you.
I'm happy with my decision
