Admittedly, I'm not that 'up on' these types of trucks, but uh, that doesn't look right to me. Offset on those rear wheels looks a bit problematic to me. And people freak about 1" spacers..
Good observation though the photo distortion makes it seem dramatic. I'm not an EC owner but as far as I've read, Earthcruiser hasn't had problems and documented failures with their axles/wheel bearings/etc. WIth any of these vehicles, I would get good answers to the following:
(1) What are the empty and trip-equipped (water/fuel/kit/pax/etc.) loads on each the axles?....have the seller spend ~fifty bucks and a bit of time, go to the CAT scale and get the printouts
(2) what are the axles rated to in their original format, was it designed as an offroad 4x4 or simply a general purpose chassis/box truck or maybe all of the above?
(3) What company did the SRW conversion and what is the "new" GAWR, what is their warranty/liability when something goes wrong?
(4) What, if anything, is modified from the original re components, parts & maintenance? Get a list. If something fails and there's an accident within warranty, who is going to be there to make things right?
I'm no engineer but GAWR is only one piece of a somewhat complex system along with suspension, wheel, tire, etc., not to mention intended use, tire speed/load rating @ PSI, maintenance, etc. I think if I were in the market for an exped vehicle that had been modified in any way from the OEM, I would want documented & verifiable answers for those questions above.......and then make a final decision if I think it is legit and it matches what I want to use the vehicle for. One thing that is odd is how no one seems to be asking for custom axles to deal with the weight& possible frame extension&modification that some of the exped makers rely on for their designs and yet are happily paying significant amounts of $$$ for hodgepodge setups....combine that with sloppy maintenance and don't be surprised when you have a failure. If the truck is modified from OEM, buyer should look at the original spec for the truck (In this case a ~2019 Mitsubishi Fuso Canter diesel which I believe (?) has GAWR ~5,700 lb. front and ~9,500 lb. rear) and will help themselves by demanding a rigorously tested axle/wheel/tire combo from the builder, esp. if they are going to trust a vehicle that is reliant on a cluster of non-OEM parts working together and paying top dollar. I can't imagine a new axle would run that much, even with install, and the peace of mind knowing you have a axle that isn't overloaded is priceless when in the hinterland.
