Hey guys, new to this group. I have a 1986 Toyota Slumber Queen. Would this be the 22R engine? I live in Vancouver BC, Canada. The motor home is in great condition and we are wanting to do some long distance traveling. My concern is with the motor, when going up large hill (Coquihalla) it crawls up at a snails pace, 15-20 km per hr. I am looking to 1) get more power 2) for an honest good mechanic that knows these motors.Any suggestions would be appreciated. Thanks all
