Another winterizing question.
In our past RV's I have been able to access the water pump to put the pink stuff in the lines. Now with this Freelander the pump is under one of the beds and would be hard for me to adapt the necessa...

Generally the pump can be adequately drained by running it dry for minute or so.
I use compressed air, even with a readily accessible winterizing port for the antifreeze. The basic process is pretty straightforward: you drain the system as usual with the low point drains, run the pump dry, and close the taps and drains, and hook the city water inlet up to the compressor with an air pressure regulator. I usually set mine at around 40 psi. Then, each faucet and low point drain is opened in turn until nothing but air comes out of all of them. If the water heater drain plug is out (and it needs to be to drain it, of course), you need to bypass the water heater to blow out the lines or else the air all escapes through the water heater drain.
Once the water is out of the system, it's just a matter of putting a little antifreeze down the drains to protect the P traps. The whole process takes me maybe fifteen minutes or so, excluding the sometimes seemingly interminable time required to drain my fresh water tank as it dribbles out onto the driveway.
