"A few axles by the road"? Really? [emoticon] We've never seen or heard of anything like that. This is 2016 not 1960. [emoticon]
Well in September 2011 on the Alaska Highway, I have seen a few axles by the road, and ON the road ....
Mile 1052 Alaska Highway :

Mile 690 Alaska Highway :

For an old truck like mine to successfully haul a heavy enough camper that is suitable to last on many trips in Canada, the main factor I stress out to travellers in order to not bend, break or stress out axles and suspension is to simply SLOW DOWN thru the rough and frost heave sections whether a large rig or a cabover camper, travel trailer, etc.
The Burwash Landing to the Alaska Border stretch (roughly 140 miles) in my camper rig tends to cover that in 7 to 8 hours....my road logs will show me average moving time in the 19 mph to 24 mph range, as overall average is more like 22 mph....I take my time and do not want to tear up my rig.
I usually will overnight in White River, as the northbound journey between Destruction Bay and White River will generally take me 3 hours and 20 minutes to over 4 hours of non stop driving just to cover 80 miles depending on the road surfaces of course.
I have had road crews mad at me while escorted thru a construction zone as I let everyone pass and just mope along at 10 to 15 mph as conditions allow for my rig, as the ground crews are rotating their arms signaling me to hurry up and catch up to the rest of the pack as I ignore it....I will not tear up my rig at their working convenience.
Like all posters say, bring either one that will suit your needs.
