I'd like to know the answer as well. I had/have (haven't sold it yet) a Silverleaf in the Beaver Marquis and I love it, I never looked at the analog gauges and it is nice to know exactly the digital read out of everything. We have a situation with the gauge cluster in the Bus, the digital temperature gauge is 9-11 degrees higher than the analog gauge and it was determined by Marathon with the assistance of Prevost that the analog gauge is correct and the digital gauge is wrong (the two gauges are fed off the same wire/sensor). I was advised the gauge cluster could be replaced at a cost of $1170.00 + labor. So I guess my point is I'd rather have the Silverleaf as it monitors so much more than the gauges, digitally
