I didn't know that such a thing even existed. The big wheels on my off road jack has been a game changer for working in the gravel driveway but it's movement is relatively static compared to a creeper.
I can see moving around, even with the bigger wheels being a problem. I'm looking forward to if the new wheels make a difference or not before I take the leap.
Offroad creepers don't really exist, just big wheel creepers. I think they are really meant more for rough surfaces like asphalt or maybe compacted gravel, and if you're lucky maybe they'll work ok on a hard packed dirt surface. Actually they'd probably work better on the hard packed dirt than on compacted gravel.
I won't really be able to comment on how it would perform with stock 1-1.5" wide caster wheels because I never even installed them. I'm taking a chance and hoping that that this thing will work for what I want with the wide wheels. If it won;t, it wouldn;t have worked with the narrow wheels either.
If all goes well, and I get my azz moving in the morning, it'll be going under the house tomorrow. We'll see how well it works, but I don't know if a demonstration will be possible. Even if I liked being on camers I don;t have a way to set up and record a video of it.
I put 6” casters like what came on that creeper on my engine hoist. Makes it easier to move around but it still doesn’t work well on gravel.
Even with the wider wheels, I wouldn't want to think about trying this or an engine hoist over loose gravel. Aside from dirt and grass, the roughest thing I'd probably try it out on is some crush and run that has been in place and packed down for near 20 years now.
The shop I work at is plywood floor. We work on class 8 trucks, mainly Volvo. The plywood is laid over asphalt tailings and enclosed by 40' seacans 2 sides and insulated tarps for the roof and walls. Natural gas indirect heat. (Can't think of the correct term...)
I'm assuming that asphalt tailings is the same thing I usually see referred to as millings here. Basically ground up old asphalt. How does the plywood work out when you need to use a jack and/or jack stands?
I'd consider a structure like that if not for 2 issues. First I want a lift, so I'd still need/want to dig a foundation and pour concrete for that. Second, asphalt sucks during the heat of summer. Being under the shelter and covered by plywood would probably negate the heat issue, but the ambient air temperatures would still bring out the smell.
Here recently I was thinking about doing a structure of that nature for a shop at the new property I'm looking at. Place two 40' containers with trusses and a roof between them. Initially I'd use them for locking storage, and maybe turn half of one into a makeshift hunting cabin (basic lights, bed, heat and air) until I get a house built and move. I'd want 30-40 foot beetween the containers and eventually I'd want to frame it in. I've got a while to think on that. I don't even know that I'm getting the property yet.
Eventually I’ll have a real garage up, but realistically that’s about 2-3 years out the way things have been going and I’m fed up with having nothing.
Hopefully that goes better for you than it did for me. I've been saying the same thing for a decade or more. Closest I got was a carport and a storage shed, neither of which ever really got set up for working in. Now I guess I'm grateful that it never happened, if it had I'd have more money into this place that I'd never get back. At least I can get the 8x16 storage building moved to the new place when the time comes. The 24x26 carport will probably stay here. Going to be kind of awakard getting the inoperable vehicles moved, especially since one of them should really be in a scrap yard. It's got parts I want to keep and I don't have a better place to keep them than on it.
