Chieftain startup beep

That rather changes the scenario, Soreinsky. If it comes out of the speaker that gives you a huge clue.

I am not ruling out anything you say and I am sorry that I didn't explain fully but this is because I didn't envisag the answers. I will explore all the answers I receive today more fully tomorrow when I take the MH out to test the theorys the kind contributers have put forward.

it might be worth taking someone with you so they can make a note of when these bleeps happen , eg ,speed ,revs ,what gear you are in ,up hill ,down hill , to try and find if there is a pattern to when these bleeps happen ,hopefully the answer will be something simple 

A long shot this ,but , has the Vechicle got reversing sensors? and some how although you are  not in reverse the system is faulty and they are picking up the cars behind you 

Write your comments here...thank you for your help. There's no rear sensors but there are front ones but alas no traffic in front.

Write your comments here...thank you for your time. The noise seemed to increase on low inclines but not steep ones!

The fact that the bleep sounds on an incline might suggest a fluid level indicator ,,such as fresh water tank ,waste tank or toilet tank 

also are the two bleeps related ,the one on startup and the bleep when driving, it could be two different warnings 

Is it an auto box if so do you leave it in N when parking as it may be that. When driving is it a speed limit warning telling you you have reached a preset limit? For the incline like HD thus may be a fluid warning of some sort.  Do you have a alarm fitted?

 Ten out of ten for you there is a fault on the front sensors. Thank you all for your help.
