Our exclusive Challenger C series diesel forced air heaters can and will heat the average motorhome to 24 degrees in roughly 5 - 6 minutes. Can your existing lpg Truma do that?  Can it do it while you drive?  Challenger can! Ask your rear traveling passengers just how cold in can be back there. 

HEATER SIZES - What is best?

2kw - Small to medium sized vehicle / boat

4kw - Medium / large sized vehicle - best all round performer both small, med and large vehicle / boat.

6kw - reserved for the larger vehicle/ boat, normally with multiple outlets required.

Engineer turned up, assessed job, spent a few hours working on motorhome fitting Challenger 4 kWh heater.

Was pleasant and informative and answered all my questions, couldn't have asked for more. All I had to do was supply a few cups of coffee.

Wish my experience of tradesmen over the last few years was as pleasant and reliable as this. Many thanks and would not hesitate to recommend ACLS to other van users.

Elaine McPherson Over the moon with the job and professionalism of fitter.
