Mechanical checks on a used van before purchase?

Normally with a used car, I take it to a mechanic for an inspection before deciding on a price. But mechanics are telling me that, with these big vans, it is too much work to get at the engine to look at compression, spark plugs, or anything. Like $400 in labor too much.
I did find a trans guy willing to do general inspections with extra emphasis on transmissions, and I figure he knows enough to get a good sense of a tranny from the outside. (Is this realistic?) I didn't ask him specifically about engine stuff.
What do you all expect from a pre-purchase inspection? And what do you get?
If you do it yourself, what do you do? I mean, I do all the basics -- drive, listen, feel, check fluids, tire dates, crawl under the rig and look for anything untoward. But I am not even a shade tree mechanic, with cars younger than me ;).

I did look at one ambulance, but it was so trashed that I didn't look at any others. I'm glad to hear they are not all like that. It didn't have a lot of miles, but boy had it been through the wringer.
I think they might better for other styles of RVer than for me, though. Numerous large windows are important to me. I'd be ripping out much of that cool built in cabinetry to install them.
As I said in my prev post, I take for granted I will be adding shocks, tires, etc. What other suspension work do you mean? I ended up getting custom leaf springs for my current van, but I'd hope to avoid doing that again. ($600)

Lately, I've been looking at retired ambulances, either with body or cab on chassis. Most all are fleet maintained to a high degree, come with 600 A alternators and with body, have an RV style ready-to-roll. You may wish to explore that route if you're looking for a well maintained vehicle.

Gdetrailer, I read your post, and thought, 'Wow, why is this person projecting their weird fantasies onto me?' Then I looked and saw that you are from east of the Rockies.
Used cars are different out west. We have no rust, and a 20 year old car here is like a 2 year old one back east. I have been buying used cars since I was a teen. Looking under the rig, taking it for a test drive and then to a mechanic is the norm.
And 200k is the normal expectation for engine and transmission out here. In my search, I have seen quite a few GAS vans with 350-450k. I am not buying them, but they are on the road.
With an older rig I expect to replace shocks, tires, trans oil and filter, and I'm cool with a worn interior and a few dents. I balk at major suspension work, salvage title, peeling paint, or any sign of engine or transmission problems.

I could really use you folks' thoughts on the 7.3. It's kitted out for camping, slight lift, good tires, shocks, brakes, charging system for my house battery. The high top is ginormous and ugly.
I have never owned a vehicle I liked the looks of. I always buy what is in great shape mechanically, and suits my needs. I don't choose based on looks, and my rigs have ranged, in my taste, from tolerable to clean but ugly. I keep thinking maybe I wanna hold out for something I LIKE looking at. But I am also impatient to move. So the ugly high top is a factor.
You are being overly picky for USED vehicles.
Buying anything with 80K-160K miles is a gamble, you are not ever going to find a used one that will suit you..
You can gum this subject to death but the result will be the same.. You will beat yourself silly, worry about everything and in the end skip it..
If you WANT CHEAP then EXPECT TO HAVE TO FIX SOME THINGS.
You will never find a used vehicle without a few faults or problems, that is the name of the game when buying used.
Most modern day engines and transmissions will have no problem getting 100K, 200K and even 300K without any major INTERNAL problems.
If I was selling a used vehicle and encountered a buyer with your demands of mechanics taking it on highway drives and exotic evasive testing to point of tearing a engine and transmission down to bare parts I would tell that buyer to take a hike, lose my number and never ever contact me again..
Do yourself a favor, up your budget, buy a newer vehicle or better yet buy a BRAND NEW one.. This way you will only have yourself to blame if you fail to maintain it..

Compression test on modern engines is very big job, but I substitute it with acceleration test. On cars finding factory rating 0-60mph is easy, but even with van you can figure out that 2 minutes getting to 60 mph is too much.
good luck on the search.

Every seller, of course, says their van is perfect in every way and they have taken great care of it.
Yesterday's van, the mech said needed $4k of engine work, plus ABS stuff. The seller said, 'Well, sure, the check engine and ABS lights are on, but it runs perfectly!'

With both, I have learned to ask before I come look, 'Can I test drive it? If I like it, can I take it to a mechanic to look it over?' Sometimes even if they say yes on the phone they say no when I get there.
My current potential van, yesterday the guy said we could not test drive it bec he would lose his parking place. Ok, bye. Then he texted me last night that we could drive it today. We meet up with him (he is an hour late) and he says only around the block, no freeway, because he is in a hurry. I say ok, the mechanic can drive it on the freeway. Then he spends half an hour arguing with me over whether it is going to the mechanic.
I would have walked away long ago if I were not having such a hard time finding a van. I did walk, last week, when a dealer told me no mechanic. But this one is now at the mechanic, after muuuuuch discussion.
Or should I buy a 7.3 with low miles sight unseen for more than I want to spend? That's another option.

He does it from an adjacent room listening to a glass held against the wall
Can't turn the clock back on 160,000 miles. The best you can hope for is a worn out engine that somehow passes a smog test.
First of all a "Compression Test" is next to worthless: A "CYLINDER LEAKDOWN TEST"
Shifty sellers change the oil and use SAE 50 to reduce blue smoke and raise the oil pressure a smidge off the "Danger Low Oil Pressure" peg
Run your finger around the inside of the tailpipe. If it comes out black and oily - BAD. Remove top of air filter housing. Wet oily housing - BAD.
Remove dipstick. Smell it. Oil burners and compression leakers leave a telltale rank smell which is embedded in the varnish on the stick. A good engine's dipstick will smell like new oil.
Take a pocket B.S. detector. If it overloads and catches fire a block before your destination, turn around and flee.
