Let me start this by saying I have a 2002 28 ft Safari Trek built on the same P32 chassis as the one you are looking at, this is the 8.1L Vortec mated to a Chevy 4L80E 4 speed overdrive transmission, being a 2005 (the last year of the P32 chassis whose heritage goes back to 1969) this one will have the beefed up 4L85E. Mine at 28 ft is built on the slightly larger 17,000 pound GVWR chassis with the 178 inch wheel base, vs the 15,000 GVWR 157 inch wheel base. One advantage of the shorter / lighter chassis is that it likely will not have the dreaded failure prone J71 automatic parking brake. I strongly considered the 26 ft version of the Safari Trek on the P32 chassis when I was shopping for mine, but ended up opting for the 28 ft, mostly due to nearly 1,000 pounds more cargo capacity than the 26 ft, also reports online say the 157 inch wheel base can be a bit more touchy driving.
Having said that you will read a lot of negative stuff online about the handling of the P32 chassis, in the 1990's motorhomes were getting heavier and heavier, mostly due to the addition of slides, gasoline coaches were also getting longer, and simply put the P32 chassis was not up to the task, therefore Workhorse introduced the stouter W series chassis in about 2003 and began to phase out the P32 series. Now with some suspension upgrades a short (sub 30 ft) P32 can handle just fine, mine has about $3,800 worth of suspension upgrades (about $2,600 of which were done by the previous owner since 2014) and on a calm day on smooth pavement it will cruise along at 65-70 mph (not that I suggest doing so) without effort. Over 70 mph requires a bit more attention and reaction speed than I care to maintain. The big likely must do or must do soon upgrades if they have not already been done are: Super Steer Bell Cranks (the factory ones may well be shot even with the low mileage, online reports suggest they have about a 25,000 mile life before developing excessive play), another MUST do is a front sway bar spreader bar, when Workhorse widened the front end in 2001 with the introduction of the 8.1L Vortec engine they kept the same inner mount points for the front sway bar, this design flaw resulted in many people reporting sheering off the front mounting bolts. This spreader bar costs about $200 and can be installed with hand tools in a couple of hours (took me maybe 3, but I had to remove and reinstall my safe-t plus, which is another good addition). Adding to that most people will say a rear trac bar is a must, mine had one when I bought it, so can't say how it drives without it. Also at this age all rubber parts should be suspect (belts, hoses, rubber bushings, etc.) this includes the sway bar bushings, and bushings in the steering linkage. I changed out my rear sway bar bushings last month, at 16 years of age the ruber bushings were at the end of their life (I installed poly bushings), a previous owner had already done this for the front end. In addition the above mentioned items I also have Sumo Solo airless springs in the back (helped with sway), Koni FSD shocks (my factory shocks had 75,000 miles on them, still had some life left, but the FSD's are better and eliminated the porposing I felt on humps in the road, also the front helper airbags have been replaced, I don't know the brand, but the new ones are red.
Finally I feel the price is a bit high even if in very good condition, this was a entry - mid level coach when new, even in great condition I could not see paying more than $22,000 and that is stretching it, I paid $20,500 for my 2002 Trek last year from a private seller, and it had over $10,000 in parts added since 2014 (fridge, carpet, all new leather seating, $2,600 in suspension work, tires, batteries, 400 watts of solar panels, smart charger/pure sine wave inverter, ....
