Our 40 has the highest fun factor, hands down. Well, in the current fleet.
With just a bikini top, it requires a certain amount of resilience, though. As in, it has the most air conditioning ever - you just can’t set the temperature nor the air volume / speed… Suspension articulation equals that of a shopping cart, thank God for aired-down 315s. Listening to music while driving - yes, but it better be loud. On the trail - lock the rear end and the truck will get a mind of its own: it’ll square itself up to obstacles no matter the sophisticated angle you intended for the approach. The driving feedback is much more raw than from either of our 80s, but did I mention it’s fun?
The 80s are of course much more refined, point & shoot machines on the trails, with creature comforts on the way to, on, and back from the trails. And practical for more mundane purposes other than ‘wheeling. But I’m glad we have the 40 in the stable.
