I have a Eberspacher B1L (NOS still in shrink wrap) that I plan to
sell on eBay in order to buy one of Karl's propex furnaces, It's 1800W
(6143.4 BTU). I was all set to install the B1L and then stopped
because I know one day I want to go diesel and I don't want to have to
change the heater again (or carry two fuels).

I think Karl's HS2000 at 6500 BTU would be plenty warm enough,
although the HS2800 at 9500 BTU might allow you to keep your pop top
up a little later in the season. If money is an issue go for the
HS2000, but fme I like overkill so when I get mine I'll pay the extra
$200 for the HS2800.
