Smails I will say sorry for the guys cluttering up your thread with their talk about THEIR vehicles.
This is why having a guide/handler is so important on an expedition like yours. With social media, easy internet access and such it is far too easy for others to detract from the experience you are wanting.
I am sure you are looking to setup a sat comm setup with global data access and I would be happy to help with that. I have been working with companies like Spot & Delorme on behind the scenes solutions and I am sure you are able to go far beyond those middle class options with your resources.
Nav and comm will be a vital part of your endeavor especially since I now see you have a serious medical condition. Again as a Wilderness EMT & ICU RN I can be a key part of ensuring your expedition success. I work with Donor Network regularly and have taken care of transplant pt's for years. We will want to make sure you are monitored for labs and other biometric indicators.
As it is clear you have the resources and desire to make this Round the World Expedition possible I would recommend you have ICON build you both the FJ43 and the Bronco. This will give you a longer wheelbase gear carrier and a shorter wheelbase tactical extreme enviro machine. Another option would be a Global Expedition Vehicle or ActionMobil larger rig as a basecamp/chase rig.
Having been to the largest offroad show in Germany and meeting many of these manufactures I positioned to liaison between you & they. To reach the position you have in life has taken time & skill, and part of that skill was knowing when to bring in a team member and delegate. Happy to help!
I give you credit for taking the time from your busy schedule to come to Expo and let this community become a part of what will surely be an expedition long remembered and discussed. Between you use of ICON vehicles and your resources to setup a team of experts there is no doubt of your success.
My full CV with references is ready to be sent to your office. I understand there might also be a background check and security clearance required. As a registered nurse I am felony free, but I sure you need to dig deeper and I am prepared for that.
Ensuring proper fuel depots, med procurement, border crossings, videography & photography documentation are all things that need to be looked at at the earliest stages of the Expedition Planning so we need to get started ASAP.
And speaking of documentation I would recommend you start working with good still shooter & someone else for video now so that backstory gets the full attention later generations will demand. We have some great people here on Expo in both of those realms and I am sure you could secure there services (it will be a premium rate but worth it as they understand the demands of expedition/overland lifestyles).
I would wish you good luck but men like you make their luck and carve their destiny out of the world other men merely stumble through.
