Auto Shifts are easy...only use it when stopping and starting off......Look at the insulation carefully in any custom built unites.....I have noticed some problems that manufactures are NOT disclosing/addressing...[though they might not be aware of them.] Long term-deteriation- of the insulation would lead to increased costs of running you unite and some discomfort in extreem weather conditions...I'm very leary of bubble wrap insulation and would perfer at least poly-iso foam blocks glued in place or ultimatly spray poly-urethane in place insulation.....fiberglass is a joke because if it's ability of holding water vapor and freezing up...I have a HVAC engineer that advises me on insulation issues that works for my local uility company...I also live in a super-insulated home-so insulation issues are of great interest to me....geof
