Risposta da John Hi Casey, thank you for the feedback. As our vehicles are predominately used in Summer, over insulating them would make them unbearable in June, July and August so this is just not something that is practical. To counter this, we offer extra bedding on request - you didn't ask for any - and also offer a "winter warming pack" that has an extra duvet and a heater that you can use at night. You elected to not purchase this winter add on. We hope you enjoy your future trips.
