Are these suitable for a 28' class C RV (to keep weight off tires when parked) and must they be bolted on, or can they be used independently?

We have these on our 40 foot camper and they work great. They do need to be attached.

I can't see why not I mounted mine on the outside of my 5th wheel camper. You for sur could mount them next to a stud as long as the rotate the speaker some

Not sure. I have 14" tires on my trailer and they are a snug fit. My guess is that they would fit. With the smaller tire you may have to do some cranking to get plates up snug to the tire which would be no problem to then level the trailer.

I use mine on a boat trailer but my boat weighs about 1000lbs. You should be ok since each tire would be loaded with 750lbs. plus trailer weight. Check the posted load rating on tire to be sure.

These are specifically made for unlevel conditions. The only concern is you have to watch the gravel. You don't want big chunky rocks under these. I had to buy two kits as one wasn't enough. I use them on a 12k Lb tandem axle 38 ft 5th wheel. Takes 3 under each wheel for me just for starters then one under the landing gear and rear stabilizers. That's 16 and gives me 4 more to add to the low side. If the campsite it any more out of level then that I don't want to park there anyhow.

Sorry I'm not able to answer this question. I purchased this item but never used them. I have a 23' RV that weight 5500 lbs.

They will bolt up, but I'd suggest a lift or level with the 0mm offset. If that's not an option, I'd recommend you find a wheel option in the 15-35mm offset range.

I am not affiliated with the design or production of these devices so I do not know the weight limitations.I just know that we have a 25' 5500 pound RV that we use them with. One will lift one side of the RV with no indication of collapse concerns.The only thing I'd say about these is you need an offset wedge to insert once the vehicle is lifted upto keep it from trying to roll back off of the wedges. Their other product has these additional wedges so I don't know why the additional wedges are with one product line but not another.

I use them with my 35 ft fifth wheel. I have only stacked them as illustrated two high. If a third one is required, I just stack on top of the center one. There isn't enough room between the tires to do three high as illustrated. They work well and so far proven to be durable.

I would not use these for anything that is suspended, like a heavy car. These are a lighter jack and work great for additional support to balance or keep a trailer from rocking. I used them on a trailer with single axle to keep the trailer from tipping back with too much weight in the wrong places since I was working on the surface of the trailer and walking around. They would work also on RV trailers to stabilize the movement of the trailer when parked.....

Your wheels must be very close together if these don't fit. Have you seen the video of them in use? They do not have to lie flat before you move the trailer onto them and you don't need to always use both. If you can't use both, I personally would not use them along with another ramp or whatever. It would be too difficult to get the level right and would negate the advantage of the system, I think.

I would say Judy should be fine they are a solid tire as long as the rim size is 15" diameter. Just mounting by yourself is a bear because shipping has tires squished in box.

I believe you would need those to fit 35 in tires. You could always check with a tire shop.

Yes they should be fine. I use a two bagger system on my zero turn as well. The tire has held up great so far.

No they won't. I purchased them for a similar application and they are huge. These are good for a beach cruiser with the big fat tires.

I thought I could use it that way when I purchased? But doing it alone is pretty tough. They cannot be attached to the van or fixed to the ground so they tend to move around and become a hazard. I would not recommend them for that purpose.

These are for single axle. You will have to look up tandem axle. Hope that helps.
