Einbau einer neuen Eberspächer airtronic D4 Plus in einen James Cook

[OldWest]

Why not use the newer models which have a longer brushless motor life, integrated high altitude, quieter fuel pump, graduated versus fixed speeds fan, etc.? The new heaters are the same size and use the same plastic case. There are various submodels including one for RVs or recreational but they all seem to have sufficient blower fan output.
