Hello and welcome Chris.

Plenty of Autosleeper owners on here, you've made a good choice (just my biased opinion of course!)
Is it a high top or pop top that you're getting and whereabouts are you? If you go to "user control panel" on here there's an option to E D I T your profile and you can add your location, which makes it easier for people to help you out, or point you in the right direction, when needed.
"Newbie" posts like this one generally get more responses if they're posted in the general chat section, but I'm sure you'll soon start to find your way around. Lots of helpful people on here.
Happy camping.

Get yourself along to a club meet some time if you fancy it, it's a good laugh and a great crowd!
Tony
