Dometic V Truma AC

[Brummycraig]

So I've been at the show today researching AC that we'd like to have fitted this winter ready to hopefully tour Europe over the next few years....it appears that both dometic and truma have new models which have inverter compressor heat pumps which claim to be more economic, quieter, smoother and draw less inrush current. The truma in the form of the gen 2 aventa comfort and dometic rxj7 2200 which are comparable specs and should be suitable for our 7.4m MH.....the show offer on domestic fitted at Tewkesbury £2200, the truma fitted at Derby £2250 (we're Birmingham so similar distance).....with both of these being new I can't find any info/reviews online, and I doubt many people will have experience but I just wondered if any of the knowledgeable people here could give a compelling reason to go one way or the other? Thanks in advance
