No current plans to hit Kazakstan, but will keep that in mind
I think our drive height will be about the same as yours. 12 feet maybe a tad more as we plan to put racks on the roof for paddle boards. What have you "run" into as problems with the height? I read through your website before responding. Hence the 24 hour delay. You have had a ton of experience with this truck and incredible travels. Does your truck not have the uphill start assist brake? It is right where your pass through modifications to place on my truck. Maybe it is the 2005 difference? I have not measured the decibels at 70 mph, but I am hoping at 60 mph it is much less than 100? I know my phone will not respond to voice commands. I took to wearing headphones when I travel alone to be able to hear the maps and music. The new GPS and radio installed yesterday should fix that? I am not sure about Expo yet. Would love to be there, just not sure it is going to fit in the schedule.
On "height" - we occasionally come across an underpass or some such that is rated less than 4.0m. We have found that most rated at 3.8m or higher
will allow us to pass as these signs tend to be conservative.
However more frequently we find entry gates( with a topping arch), trees and wires an impediment. Many places do not trim trees beside the road
and simply allow trucks and other high vehicles to brush the trees. Thats OK for a box truck but with AC, solar panels and other stuff on the roof our vehicle
is a bit too fragile up top to simply push brush out of the way. If I had it to do over again not only would I make the truck a little lower
but I would try and make the top 0.5 meters tough enough to push branches out-of-the-way.
I have already lost one "on-roof storage box" to trees in Peru - an that vehicle was considerably lower.
We don't have "up-hill brake assist" - our truck is a manual. Thats becoming a problem for my aging knees. In "off-road" or slow traffic conditions
where there is a lot of stopping-starting-gear changing my left knee is pretty much shot by the end of a days driving.
I enquired at at our friendly German UNIMOG expert about upgrading to automatic and was told "its not too difficult as its mostly electronic,
but don't do it as the autos are trouble". (thats a paraphrase).
Even with the manual we have has some shifting problems. In Kyrgyzstan I had to get Rob P to walk me through the U500 transmission "learning process"
as it was dropping out of gear while driving and occasionally giving a error code and refusing to change gear.
When I recently left the vehicle in the Netherlands I experienced a couple of instances where the transmission would not shift into a gear while stationary.
Had to resort to the emergency manual shift knob in the console.
Wish I could put an Allison in the thing.
We mostly drive at 55mph. In Europe this fits well as trucks are limited to 80/90 kmh and we just join the long train of trucks.
Its a bit more of a pain across the plains in USA but we rarely are trying to make any large distances in a days driving.
Nina and I are staying in Phoenix until late May so if you get this way drop me a message.
Then back in the Seattle area for a week before returning to Europe
