Well, my BAL was definitely worth the money because it was free !! Thanks Rick Cathey !! I used the blocks of wood for the first few years and they served the purpose. I never really had a lot of faith in their stability, though. I mean, a little rain - the ground gets soft - the wood sinks - the PUP falls off the blocks, etc - etc - etc. But I am, by self confession, a 'worst case scenario' thinker. Besides that - you never needed the same amount of wood chunks for any given camp site. So there would be blocks of wood laying around. Next thing I know, there's my kid tossing a piece of my leveling wood into the campfire. Once I got the BAL and started using it, I was a damn fool for not buying one sooner. Slide it in - crank it up. No trying to stop precisely on the middle of some chunks of wood. And when I did the wood block thing, my camper 'squeaked' when you walked around in it because it was essentially rolling back and forth slightly. Not with the BAL !! I use the BAL + chocks on both sides of the other wheel - no noise, no movement. I will confess the BAL is a PITA to store. A lot of guys use insulated pizza delivery bags for them. I would, but I've just never gotten around to buying one. I should, because I'm getting a spot in the fakie wood paneling under my dinette where the BAL rubs up against it. One of these days...... Yeah - I give them a big thumbs up !! I say a BAL is necessary like toilet paper. Yeah, you can use other stuff in it's place, but for the ultimate comfort and peace of mind - it's good to have one. Please, don't squeeze the leveler !!
