Hmmm,i guess I can comment on this,
Having owned 3 now(sold 2) I can confidently say,I don't know what I would do without one,the do have their failings at times
The 816 was heavy and woefully underpowered for highway use,although I probably logged more miles on it than any other MV I've ever owned,all over the east coast!! But just the ticket for moving stuff by yourself around the yard.
My current M62A1 has better power and is quieter to operate,but is difficult to get parts for the wrecker bed,it will haul butt over the road,and will lift 30K with no problems.
My M553 GOER wrecker was at best,a yard ornament while I owned it,Papabear and the CAMO group have done more to it than I ever did,but that's a one of a kind wrecker,it belongs in a museum.
All in all,i wouldn't mind having another M62 or M62A1 just for the simple reason,if 1 wrecker is good,surely 2 would be better!!
