What is this? A tag team team event? Did you two coordinate outfits today too?
Yep...you use them for walls or to support buildings. You know...what they were made for. Not for point loads.
Cinder blocks are designed to provide support and add stability to structures. That is what I am using them for. Those wood blocks you use designed for point loads? I don't know, I'm asking you because you might actually be able to teach us something.
My advice is not for you... you obviously know everything... MY advice is for those who plainly admit they DON'T know and who might make bad decisions based on your bad advice
Seems to me that you're the one that knows everything. You have over 7000 posts. You must either know a lot or just really good at keyboard chatter. And don't worry about me taking your advice. I can honestly say that I had never taken any of your advice and probably never will but hey, thanks for letting me know.
Bad advice, huh? Let me provide a recap of our (not so) impressive exchange and let others decide which advice is good or bad.
Me: I jack my trailer up but I use cinder blocks.
Tag Team: They will crack.
Me: They used to hold up a motor home. I think they'll be fine.
Tag Team: They will crack.
Me: If used properly, they will be fine.
Tag Team: I tried to swindle my buddy out of a hundred bucks to prove jacks are stable. He had the bright idea of running full force into my boat that was up on jacks. I didn't try to stop him because there was no risk. Turns out I was right but now I can't figure out how to get my buddy to pay up.
Me: Well, I think there is at least some risk there, but ya, I wouldn't let anyone do that to my boat.
Tag Team: Yes you CAN build proper pillars and use enough that if one fails the rest will take the load but DANG you have to work soooo much harder than placing a few stands.
Me: Right on! See? You get it! Cinder blocks will be fine. And also, I'm already spending most of my day winterizing, a few extra minutes won't make a difference.
Tag Team: I wouldn't bet my life getting under something supported by cinder blocks.
Me: ya, not a good idea.
Tag Team: But I would for a couple sets of jack stands, wood blocks and hydraulic jack.
Me: Really? You would bet your LIFE on that? Ya know there is a wrong way to use jacks and wood blocks too right?
Tag Team: but I am using them for what they were designed for besides, cinder blocks can only hold up walls and big heavy buildings.
Me: I use cinder blocks as they are intended for too - to support things but I use them for things that are much lighter than buildings.
Tag Team: I don't use jacks because I park on grass and play music for my trailer.
Me: Ya know, tires can sink into grass, right? Maybe put a piece of plywood under them?
Tag Team: Nah, it'll be fine.
Me: So that works for ya, ok. How about my cinder block method?
Tag Team: Bozos will kill themselves.
Me: Well, like I said, use them properly though.
Tag Team: Well, you just think you know everything don't cha? and don't take my advice.
Me: ??? Ok, I won't.
Along the way, a couple other posters mentioned their methods and wood blocks seemed to be the preference. To the OP, seems you have some options and if I could add one more: One of my buddies over inflates his tires a bit to prevent flat spots. He doesn't jack his trailer up.
Happy winterizing.
