We are looking at a 1990 Newell with an 8v92 and a 6 sp (I think) 135k miles. What issues should we be aware of? Has minimal water damage above entry door, crack in wall rear side of dinette. Some other minor things need attention, but nothing major. Also anyone know approx. hitch capacity of the coach? Kind of flying blind on this one. Has a combo diesel/propane water heat but I can't tell if it involves the ebgine coolant or not, but seems to work fine. Could use some help as to what to look for, Thanks in advance, Mark

Actually I did. My questions are 1990 era related as there is not a lot of similarity between the 1990 We're looking at and the 1982 we had. It was a single axle, 6v92 all mechanical. Had a 3000# hitch. Sold because we didn't use it enough, but things change. I'd like to pull our 26' stacker.
the tranny in a 1990 is an allison hd740 and it is a 4 speed. i had a 90 before i got my 02.
they put many different hitches on so we probably cant help there.
as for heaters, mine had 3 propane furnaces. i know some had a diesel fired system that is no longer made. not likely it had both.

My 1993 is capable to tow 20,000 lb. with proper hitch/brakes etc. As you know no two Newells are exactly alike. I tow a trailer with my Grand Cherokee and it handles it easily. Several others on this site have pulled heavy trailers, Larryweikertsr being one of them. Hopefully they can add more detail.
There were a few places (especially below the windows) where cracks appeared. Tearing the wall paper off revealed a seam in the plywood wall sheathing. The compound that Newell had used to smooth the joint had deteriorated from age and moisture. I resealed and applied new wall paper.
I moved up from a 1978 Newell so I can relate to the learning curve. You will find the basic construction of the coaches to be quite similar.
I cannot help with water heat. Mine is all electric forced air....No propane.
Look in the water basement on passenger side. It may have a Raritan electric/engine coolant water heater, which would have 2 coolant hoses going into the side of the water heater.
WE run a 42 foot 90 and pull a 30 foot ATC stacker
Since we run a lot of grades we rebuilt the tranny,and added a tranny cooler along with changing to a 170 degree thermostat in the engine
If I manage my RPM'S and run around 1750 to 2000 RPM's I can pull 8 to 15 percent grades and stay under 205 degrees
My stacker is 10k pounds empty before I add a jeep wrangler, RZR and boat and trailer on top so I opted to rebuild and beef up my hitch; 6 years running and about 6K to 9k miles a year with no issues so far

I pulled 26000# behind our 94 for over 200,000 miles. Initially had some over heating problems on long grades. Corrected the problem with installation of a slightly larger radiator and the learning curve of properly maintaining rpm's and shifting. This may not relate to a 1990 as ours has a Series 60 and the trailer is full air.

Thanks for the info. I would have preferred the 60 series as well, but for the most part the coaches with 60 series or Cat are out of our price range. We have the 60's in our farm trucks.This is only a 4 sp. Salesman told me a 6 but not so. This will be used in Western US and Canada for the most part so I want to get it right.
Trailer has electric/hyd disc brakes.
I understand the Newell doesnt use hyd levelling, rather depending on the air suspension. Is that correct?
Thanks for the replys
History: There were a few pre-1993 Newells that had hydraulic levelers but the vast majority, probably 90-95% had air leveling only. As the coaches got heavier, the disadvantages of hydraulic levelers getting stuck in soft soil or hot asphalt pavement made air leveling more practical.
Newell primarily used the Allison HT 740 in conjunction with the Detroit 8V92 from 1984 through the first part of 1993 when the use of the HT 741 (the electronic version of the HT 740) started to appear. The Detroit Series 60 first appeared in Newells during the 1994 model year, likely with coach #464 being the first although some Newells built after that still had the 8V92 through #376, a 1995 model. Even after the Series 60 was added, some were built with the HT 741 4 speed and some with the Allison 6 speed World Transmission through at least #385. After that the Allison 6 speed was almost universal in Newells until 2005 when the Cat C-15 and the ZF 10, then ZF 12 speed transmissions were introduced. Although some Newells after that used the C-15 with derated torque with the Allison 6 speed World Transmission, it was late 2009 before the Allison regained primary usage in Newells. With coach #1405, a late 2010, Newell switched to the Cummins ISX which it uses today. To the best of my knowledge, all of the Cummins ISX engines were mated to the Allison 6 speed Transmission.
The 8V92's were more prone to overheating on long grades than the Series 60's so watching the coolant temperatures, keeping the rear radiator clean and keeping the rpm's up around 2,000 on long grades is more important especially when pulling heavy loads.
