Depends what the under carriage looks like. If it were all banged up, probably not. If all the skids looks pretty clean with minor scrapes, I'd give it a thumbs-up!
It's just that many folks out there don't know what to look for.
They'll see this totally stacked (built up) off roader and think to themselves, " Wow! I could go anywhere with that!" without considering just how hard it's been wheeled.
Not a problem, if it has been wheeled hard, just that someone with experience and knows about these things would know better suited of what to look for (regarding damage) and not mind the mods and maybe even some minor dings.
So, the short answer to your question, is I probably would buy your rig. You've never posted any pictures of your rig scraping along boulders or trees, hung up on rocks or having to be winched out of 4 feet of water. All your adventures seem reasonable and I'd know what to look for when examining your rig!
