Long distance traveling in a '67-'72 suburban

[CDA 455]

Instead of ordering or buying a '17+ rig, I'm thinking of buying a restored '67-'72 Suburban.

I want to travel fulltime and tour North America with a reliable rig, but I'm really discouraged by post-covid production quality of trucks AND what the rig electronics is evolving into.

With the ability of an entity being able to 'upgrade' a rig's software like it was a smartphone sends up huge red flags for me.
In addition; the gov want to put electronic kill switches on all new vehicles starting in '26 sends up even more red flags.

All that being said; I would opinions/thoughts/suggestions on the idea of long distance traveling in a '67-'72 rig.

Basically; a K.I.S.S. kind of rig/manual everything:
1) Locking hubs
2) T-case
3) Full manual-shifting auto tranny
The only luxury would be A/C.

Good idea?
Bad idea?
Ugly idea?
