Depends on how much you like it I guess , but the 915 has kind of a small grey holding tank ,about 13 or 14 gals , and if it has a sat dish its probably a crank- up winegaurd , they only are good for standard def tv , and only work well with direct tv , dishtv you have to move it to get the other sat for more stations
If it has a soft floor at the dr check under the shower pan , its probably been leaking , also check how well the grey tank is hung because its lag bolted into that area of floor underneath
I think if a person is up keeping a camper in good shape it might not have this many things wrong with it , I`d look closer at it to make sure thats all that needs fixing
