trailblazer is the go if you have room,have had a waeco 35l for 2yrs,runs 24/7 and has broken twice,it doesnt have too hard a life but still not impressed with it.I bought it only for the size as I didnt have much room to fit it in.The first time it broke 2mths out of warranty but I cannot complain about their warranty as was fixed no questions asked, but to do the same thing 12mths later again am not impressed.Trailblazer is used for medivac ops here and o/seas which says a lot for their quality,mind you they also use Landys which I am not a fan of!!!!!!!!!
