    When that seal goes out on that can, you will be pulling water in when it rises to the level of the hub. Sheesh......

    Many states have banned on road use of MV's. Even Canada has made driving them difficult. In a flash all of your work money and work is wasted. Watch your State Legislator closely! Band together to make sure this does not happen. This can be done by setting up an automatic send of all State Bill proposals. Once it's law, it's hard to get it changed.

    Dust... different issue. making a wide thin snorkel between box and cab (same square footage just different shape) would IMHO be a wise change. doing that would make it very similar to the 939 setup

    939 series cans were designed to be submerged. contingent on a seal built by the lowest bidder. Plenty have been underwater for long periods of time without issue. Fording dept for a LMTV is 36in. Well below the top of the tire which that intake appears to be over it. 99.8 percent of people are not folding rivers in their camper. A simple slip on pipe accounts for higher water fording but then you have to worry about your exhaust. The LMTV fording kit for 50in is only an exhaust extension.

    IMO LMTVs should stay as far away from high water as possible wether stock or modified. Military or civilian.

    Look closely at the where water would end up being sprayed, even if just driving in a rain storm.

    I don't plan on high water cruises, but I would like a greater margin than what that offers. High water travel across fast streams is best left to the Russians lol. Every single hose clamp and seal would to be perfect, or it's going to be expensive.

    I'd like to hear from those who have forded in any MV in deep water with a snorkel or a mechanic that had to fix the failures : )

It was designed for quick dismantle in the field, not space conservation. RV people have tried to redo this area. I think it is somewhat of a waste of time. For example, the spare tire is going to take about the same area, whether it is left where it is, or stuck on the back of the RV. If you are trying to regain the space by moving thing around, consider dovetailing things like a small gen, a 12 volt compressor for back up, into that area. Put things on slides, whenever possible. Maybe put the intake on stilts or something and utilize the space below it better.
    Cab tilt will be easy. One snap collar will separate the air pipe under the cab and up she goes. I am also planning on putting the expansion tank up there I am certain I can make a better use of space with box and steps there and the tire pushed to the rear(lower overall length for a given sq/ft).

    I don't like it that way likely your not fording over the top of the tires but, there is a lot of spray kicked up from those tires just drive down a muddy road like I do all summer there are times I cant see out the side windows I would look at the Isuzu npr trucks they have a low mounted air cleaner with tall skinny duct work attached to the cab and nothing more than a compression seal. its not water proof for fording but works good to get clean air from above the cab

    Only issue there is that if you want to run your engine with the cab up to work on it, you will have an open intake. That is dangerous.

    Do you have a picture of what the FMTV high water kit looks like? I have never actually seen one.
