Hi Luggnut
you don't say if it's petrol or deisel small block or big block
i suppose 120 thou is quite high for a petrol but then again 1 in 6 hill for a long way is quite a drag for a petrol engine considering the weight you'll be pulling
a deisel should have more low rev's grunt than a petrol
if it's not burning oil and starting up ok i suppose a compression test can't hurt
JMHO hope it helps

Hi Luggnut
don't forget you will lose a little power on LPG
my winnie runs on LPG as well and i was told to expect a slight reduction on power when climbing

something to do with way lpg burns

mine seems to like lpg best on one of the hills i did switch and i got a bit more power ,but embarrassing being overtaken by all an sundry

Mines got a 6.5 Chevy diesel and pulls like a train on hills but has only done 20k miles. On a trip back from Cornwall recently we flew past all the trucks on the hills and I keep it to 60 on the flat so we don't take a big run up.
