No! I hadn’t seen that before! Thank you Bob that’s great. My R needs an engine in the fairly near future and that MH could serve me while thats down. But the guy hasn’t paid for the old pete yet so hopefully he comes through in a few days.

I use to run a 1984 MH 613 with an E9.   They are good trucks and the cabs will be around a long time.  Quite a few of them around as parts trucks.  Lot of frame parts same as superliner. Now working on a 93 MH as a show truck

You ever driven one bob? You like them? Im totally ignorant about them. There’s not many macks where I live and all that is here are a few old R models the occasional B that is someones toy or project. Used to know a milk hauler that had a superliner with an 8V silver. Its long gone. I don’t know that I’ve ever seen a MH in person. Lol

The 1st pic is one of the 21 MH's that we had at the companies that I was involved in as a teen & into my mid-twenties.  The 2nd is a friends family business. I posted the 2nd just because it seems that no matter how well they're taken care of the front corners just seem to take a beating.

This is excellent information and informative. I appreciate all of it. I knew there would be several here that could offer some insight and its fun learning about a truck i know nothing about and seeing pictures if nothing else and talking to good folks.

You’re right. I’ve studied those pictures some more and something looks off about the left front in the straight ahead picture. And the truck is sitting in a completely different place in the left side picture vs right side and straight on. Good catch hippy. And if its an optical illusion of some sort a visit in person will clarify. 
Its on facebook and probably more pics but I don’t have facebook. That said i wont make any deal for it before I see it in person either way

The front corners of the cab are removable fiberglass panels. Easy to fix by the way of general fix for fiberglass. The front turn signals look just broken off or removed and their pedestals are up above. The spots don't look broken. The lights themself are standard lights you can purchase from SLC lighting or others. Overall the truck looks quite solid on the pics. MH has chassis similar to 2nd gen Superliner with only difference in the front spring front brackets since they have hinges for the cab integrated in the castings. MH's are typically shorter than RW's so chassis are less stressed during the service life. And supposed to be less cracked. But the particular truck is quite long for a MH. The engine is probably E6-350 for 1985-1988 (or 89) and later ones had E7's. MH613 means Mack engine tandem rears.

The engine, tranny, rears and the chassis are typical Mack stuff. Not far from an R-model. Front axle and springs are similar to Superliner as said above so no trouble to find spares (no more than for a R-model).  Specific parts are the cab which is rust-free but may have stress cracks. The one on the pics looks very solid. Typical issue is the shifter linkage where multiple joints wear out and bring troubles shifting into a particular gear. Some spots are relatively easy to fix (by machining) and some not. Complete linkage is difficult to get. Also when you're up in the cab and far from the tranny you barely hear when it grinds being shifted not in time. That's my observation in relation to an R. Windscreens aren't for sale at every corner and many trucks have repairs in the plates where cab shock absorbers fit. Cab airbags aren't a trouble to locate. Cab lifting pump may be leaky but that's just a hydraulic pump.

While driving you must keep specific road orientation relating to an R-model since you seat much closer to the outer side of the vehicle. Actually you're riding the FL wheel so you must keep yourself up close to the median white line on the pavement otherwise you may hit a pole by RH mirror. Maneurity is like of a big car in relation to a conventional. Of other typical MH issues the threadle valve in the cab use to get stuck having long steel plunger in aluminium base but that's when the truck is parked for a long while. Anyway worth to take apart, clean, put grease and install solid top rubber cover. The grill parts are hen's teeth as pointed above but those on the truck are fine judging by the pics.

On the postive side aside of maneurity you have perfect access to the tranny and easiness of clutch replace if needed. 

Ugh, and always be patient and keep attention while getting off the cab :)

I will say you'll love working on this truck. I love working on our MR688. You tilt the cab forward and EVERYTHING is right there! Front of engine, back of engine, sides of engine.... Transmission? Once again, everything is right there. You can put an A Frame over it to lower trans out.
