Does this look sketchy to you?

A guy devised this to level the camper because the fridge needs to be level. I think it's too much stress on the driveline. Maybe if he used chocks to hold it, then put it in park it would be better. What do you think?

Not sure I see where the stress on the driveline is. The truck thinks it is on level ground. Almost looks like you could leave it in neutral and it would just sit there.

It looks to me like the ramps are very steep, More that the driveway behind the rear wheels. So it would be trying very hats to roll down the ramps.

As long as the ramps don't slide it looks OK to me.

No because at the same time the truck would have to be trying to roll UP the driveway, hill or incline grade. The truck as stated doesn't know where it is only gravity and "the shadow knows"

First thought would be about “chocks”

Rear wheels should be chocked.
Front ramps should be redesigned so that the wheel can descend into a dip of a few inches for security, and the underside of the ramps should be “grippy” with a rubber like tread.

OSHA, MSHA or US Military would not consider that good engineering.

The top board of the ramps should lay over the top of the vertical member. The wood should be in "shear" , not the bolts holding it together.

I'd at least chock the rear wheels.
I also agree w/ kerndog on the ramp design. Not how I would have done it, but if it works...

The only stress is on the front suspension - pushing up at about a 30 degree angle. But no more stress than hitting a pothole would cause. The ramps must be fixed to the driveway 'cause there's no way you'd drive the truck up those otherwise. I sure wouldn't crawl under the truck like that though !!!

I'm no engineer, but that's the same thought I had. The way those ramps are built look like a disaster waiting to happen (to me).

It's hard to tell in the picture but I think it's designed that way already. He just has the outer 2 vertical members running past to sandwich everything together. The inner ramps that are supporting the weight are sitting on top of the verticals. But it's hard to be 100% without a better picture.

If it was a Cummins truck it would crush those puny ramps...

Does the fridge not work because of the propane?

Yes, they need to remain level.

maybe it's just me, but i would have made those ramps out of steel, welded together, with rubber gripper strips bolted to the bottom.
definitely chock the rear wheels, and if that would be a semi-permanent parking spot, i would think seriously about sinking some anchoring points in the driveway [front and rear] to chain the truck fast so it couldn't possibly move in either direction while up in the air.
of course that's just me thinking.
your mileage will vary.

It doesn't matter if the refrigerator is level unless you're using it, right?

Are they planning to live in that or something?

I think putting the parking brake on real hard before putting the tranny into park should work okay

It looks like a great thought experiment. If the truck in the photo was in neutral with no brake applied, which way would it roll? Or would it stay stationary?

Seems like a lot of trouble to go through for a refrigerator (not to mention the potential for disaster). I probably would have just found a way to level the fridge, or just put my cold stuff in the fridge inside the house...

You really have to cool down a propane refrigerator before you put food in it. I am sure it is a temporary situation while they pack the camper for a trip.

And especially after that "Parking or Emergency" brake you would think no one would have an issue with it holding. Yes it would be extra safe blocking the rear wheels or putting wheel chocks there but both the parking/emergency and trans PARK mode should hold it no problem.

Great point as they don't look like they are too portable or intended to be used anywhere but temporarily in their driveway.

I'm looking at them differently "those are the biggest front wheel chocks I have ever seen, no chance in my mind of that truck rolling down the driveway with those chocks!"

"Romance in the Lance" might be a little sketchy ifn you catch my drift.

I always run my LQ fridge on house current or 12V before leaving on a trip so it is cold when I put food in it, then turn it to propane when I am ready to leave. But I generally think with common sense in advance...

I see that and cringe but from a physics standpoint it is valid.

Creepy looking but valid.

I would think that extended time on the ramps would deform the front control arm bushings though.

The way the front ramps are built is questionable to me. I would think they are a pretty aggressive lift on the front, and the build construction could be better. I suspect putting the truck on those front ramps is pretty nerve racking, simply because of the angle, my concern would be of just one ramp sliding. One ramp sliding just a few inches would cause some serious shift in the weight distribution.

That 1st step out of the cab, once its parked would be exciting, and getting back into the truck to move it wouldn't be much fun either.

I must admit, I've seen much more sketchy camping set ups then this one. Those people can take sketchy to a whole new level.

Ramps aside, the truck is more level than it would be if parked in the existing driveway. One should see some of the hills in San Francisco that people have parked o for years

Seems it would be MUCH simpler to level the refrigerator inside so I'm guessing it's for more than just the that. But it's hard to tell how sturdy those ramps are but they appear to be fairly well built. I don't see a problem as long as ramps are sturdy and parking brake is set.

Pretty much impossible to level the fridge inside. Most RV fridges are built right in. My only issue would be those ramps. It does appear that the load-bearing section is in shear.

My second thought has little to do with engineering,
it is the truck owner should call his insurance company and ask
“Will my policy pay if anything goes wrong with this parking set up?

Better know in advance than risk it.
