    12V Compressor vs HP Air Tanks - Pros & Cons?

    Air compressor test. Found this again thanks to a posting in the sand ladder thread. http://expeditionportal.com/overland-journal-air-compressor-test/

    Your idea should work, but I'd rather see a tank on that shelf than a water jug. The jug will block rear vision and that always bugs me because I like to keep a close eye on the the highway patrol cars that tend to sneak up on me while I am cruising. A flat, pancake tank should work on that...

    12V Compressor vs HP Air Tanks - Pros & Cons?

    Try eBay and CraigsList. They were around for quite awhile before they finally sold out. I think they were just too expensive for market conditions during the recession.

    12V Compressor vs HP Air Tanks - Pros & Cons?

    I got one of the single cylinder versions of that compressor for $400 just as they started to clear them out. Puts out 12CFM free air and requires no plumbing for OBA because it has its own power switch, pressure switch and expansion tank. Just wire it to the battery and you are good to go...

    12V Compressor vs HP Air Tanks - Pros & Cons?

    A portable compressor presents the same storage problems as a tank. Tank is fast, but a good compressor just keeps going and gives you the option to run air tools later if you plumb a tank or carry a portable tank. I have a Viair 400P in one truck and a Warn SPI OBA in the other truck. The...

    on board water system

    You may want to read the literature on air pressure and PVC pipe, and develop a better understanding of the physics of stored energy in compressed gas vs non-compressed fluids. The pressure rating of PVC pipe is for water, not gas. Any tank with good structural integrity is probably fine with...

    Gravity feed without a vent would be dumb.

    Traction Ramps / Sand Ladders

    Yes. I have 35x12.50 Toyo AT-IIs, limited slip in the rear, lockers on both axles, 12K winch, OBA, internal beadlocks, and I still carry ladders, and soon will have a pair of MaxTrax. No trees or even bushes where we normally go and summer temps are brutal, so the ladders are good insurance...

    Traction Ramps / Sand Ladders

    Obviously, I wasn't there, but one of the advantages of sand ladders and mats is that they distribute the load of the vehicle over a larger area and thus reduce the likelihood of quickly sinking into that muck. I have a pair of aluminum ladders approximately 5'x1.5', and I just this morning bit...

    Yeah, but if you don't dig yourself in then you're not really stuck. It just seems that way....

    Traction Ramps / Sand Ladders

    Before I'd pay $100 for used Smittys, I'd go $150 for a new set of Maxas. I am going to get the MaxTrax to augment my pair of aluminum ladders because I was in a deeeeeep sand stuck by myself in November and I realized that I wasn't quite as prepared as I thought I was. With 4WD and both axles...

    Traction Ramps / Sand Ladders

    If you do a Google search, you will find that the SmittyBilts do seem to have a tendency to crack and disintegrate. The hot ticket seems to be the MaxTrax at $300/pair, but the Maxsa Innovations are half the price and sorta/kinda almost as good. Overland Journal did a comparison test a few...

    Hi-lift versions

    The reason was probably sloppy Chinese manufacturing. You can get some decent stuff from HF if you are careful, but even their good stuff is sometimes crap, particularly when it comes to mechanical fit. Notoriously bad threading on their attachment points. I learned the hard way to test...

    Math Question

    Maybe yes, maybe no. Tire manufacturers are very inconsistent when it comes to actual dimensions vs nominal dimensions. The only thing that matters for OP's purposes is the OD or circumference of the tire, and that OD can vary by more than 1/2" from one manufacturer to another for the same...

    Math Question

    What's a CJ major? I have a guess, but not for polite company. Go to the manufacturers' websites for your old and new tires, look up your specific sizes, and get the revolutions per mile for each size, usually stated at 60mph road speed. Once you have those numbers, it's easy to do the calcs...

    SuperDuties are huge. There has to be space for tanks. Look at the FrontRunner site for their tanks that might fit the front footwells (behind the factory kick panels). I think they have a flat tank that can be mounted on the steel panel at the back of that giant cab, behind the rear seat...

    Another OBW Project

    My initial thought is that for only 5 gallons, it's not worth it. Just put a jug in the bed. I'd also rather see the pump put some place where it's less susceptible to damage from rocks and logs.

    Where does it become to modified?

    Somebody on this board is selling aluminum drawers for a Cruiser or Rover and somebody else is selling a plastic drawer unit that might fit. Check the "for sale" section. I saw those a week or so ago. I had one of the plastic drawer units in my old truck for years and it held up surprisingly...

    Where does it become to modified?

    What about something like a TruckVault behind the rear seat? fridge can go on top of the truck vault. You can probably find a hitch rack for the bike on CraigsList, cheap. My truck is about halfway between a nice hunting rig and an expedition rig, and I love driving it but things like the...

    If the water pipes are outboard of the frame rails and the exhaust is inboard, heat should not be a problem for them, but you could have a sheet metal shop fab a heat shield if necessary. As far as the crossover goes, I have to admit that I haven't been under a SuperDuty for a long time, but I...
