Webasto halt!
I have had Webasto markings in my motorhomes for several decades. The first was an old 14 year old Type 2 VW bus in which I had to replace everything except the heating. Installed on the ship, a little oversized almost two years ago, it is also great. Easiest operation. Let's see

Webasto Evo40 kit practical for renewal but be careful with the configuration
Point n 1 Bravo SVB for the fast and efficient delivery.
Point n2 On the product, the presentation should be more precise on the part of Webasto and from the outset offer additional options to the kit or the possibility of an "à la carte" kit. Example length of the exhaust outlet for example, longer hoses, etc.
In any case, in the event of replacement of an old installation, it is advisable to take the dimensions of the various existing accessories. All the more so if the space is difficult to access and you do not want to return there for the next 10 years to replace an existing one. undersized filter for example.
