Ok I'm back, wife is settling Mia who is only 5 months with a horrible cold again!! bless her.
Well, like I said what a great bunch we have here, I must say I checked a few forums before joining one, some of them were ghost towns with most subjects unanswered and very little activity.
Cheers Muz for the starspangledspannerman tip and thanks Scotjimland for the link to contact.
Cheers too Ehuplad, lebesset and Arenquerojo regarding the LPG connection issue.
Arenquerojo, I deffo have two LPG tanks, one massive one that takes a whole cargo cupboard, it was near empty when I collected RV put £35.00 in and got half a tank (shown on the actual tank, turns out the gas level in cab is just a set of pretty lights as it said it was full when empty nearly)
What was shocking for me was the fact it had not run on petrol for 3 years!! so I put £100 in and got 1/4 a tank lol!! lordy lordy a £400 fill up job!! mind at 10mpg it would soon go!
ACME screw adaptor sounds about right as its spent 90% of its life there in Spain and Benadorm, I'll check and see how its threaded tomorrow so not to waste money.
I know the bottle connection and hose connects to the LPG tank via a seperate connection, like I said I guess thats for them red/orange calor bottles, sadly I don't have a bottle otherwise that would have been great just to test the system is all working (e.g cooker, heating and hot water).
Engine LPG system was fitted in York, but Not the greatest job in my eyes, guys that serviced it said it was a surprise it ran as most the gas would have been leaking due to a bodged tap in point at the inlet, I must say it ran gutless on GAS hence I choose to drive it home on petrol MUST GET THE LPG SERVICED TO BE SAFE although it runs as sweet as a nut on Gas now
plus it was running NGK plugs which they said is a BIG no no!! as they also service the Lincoln limos and have seen countless examples of exploded air filter housing's and even damaged bonnets due to the NGK's misfiring on gas!!! and yes my housing was a mess due to a big backfire at somepoint, Winnebago wanted like £250.00 for a air filter housing so I went and got a cold air induction K&N for £70.00 Now have a real throaty induction noise lol!! what with Gibson stainless cat back 5" bore and filter it sounds like something fast!! until they turn around
Anyway I'm still looking for anybody that has a spare hour or two that lives local-ish and willing to show an idiot the obvious, I'll be more than happy to cover costs (unless you drive a 7.5 V8 Winnebago cos thats just outright silly

) I'm around anytime as I'm off work longterm due to this darn illness, hence the RV purchase and getting away for a few months or more.
On a side note I'm trying to T-Cut and polish entire vehicle hoping to NOT have to pay mega money for repaint, two weeks in and about 1/4 done ha! ha!, its a light blue and cream colour although I thought maybe it was once white hence why I thought of getting it painted then set about T-Cutting but its not coming up white and I can't find hardly any info or libary photos online to see if it was in fact ever white
ANYWAY A BIG THANKS YOU TO ALL!!
