I owned a 34' 1989 Pace Arrow. I owned a 454 chev. Problems I had.
1. Bubbling of fiber glass on side.
2. Rear springs were Moryde rubber. I went through 3 sets in 8000 miles under warranty. My MH always sagged on one side in the rear.
3. Manifold warping. Replaced on warranty.
4. generator door would pop open due to heat when running the generator. I re-enforced it with aluminum angle. solved problem.
5. That MH is easily converted to use two power cords so both A/Cs can be run on shore power.
I tried to get the MH re-springed with leafs on rear. Nobody would attempt it. If I could have got leaf springs under the rear I probably would still own it.
