This is some advice from http://www.scottishtourer.co.uk who have over 25 years of motorhome hire in scotland.
Driving a hire Motorhome, Motorhomes can be quite large and you may find the thought of driving one a little daunting. In reality, it is not as difficult as you might think. Motorhomes are essentially large vans and should be driven as such. The main thing is to remember that “slow and steady wins the race”. Here are a few tips to get you started safely and comfortably: 1. Size Matters Know the height, width and length of your hire motorhome. I would suggest having at least the height and width written down inside the cab somewhere (in metric and imperial) in case you come up against any unexpected road width or bridge height restrictions (in Scotland heights are also in ft and inches).
2. Mirrors Before you start driving, make sure your wing mirrors are correctly adjusted and use them frequently. On the Narrow roads around Scotland give way to the trucks they will not give way to you and you dont want to damage your hire motorhome when on holiday in Scotland, Not having a central rear view mirror can be a shock but you soon get used to it – modern van mirrors provide excellent visibility. Note: Although many vans have blind-spot mirrors, not all do. Make sure you understand what you can (and can’t) see in your mirrors; you may have a blind spot just behind the cab door on each side of the van. 3. Plan Ahead and Look Up! When driving, don’t try and rush. Take it easy and look well ahead. Remember to be aware of overhanging trees (this is where the most damage is done our hire motorhomes when touring scotland), cliffs and other height restrictions and take care to position yourself centrally within your lane when driving. The speed limits for motorhomes in the UK are the same as for cars for motorhomes with an unladen weight of no more than 3,050kg.
4. Cornering Technique Cornering in a motorhome (especially a larger, coachbuilt or A-class motorhome requires a little more care than in a car: • Slow down well in advance of corners and be brake more gently than you might do in a car. • Aim to finish braking before you enter the corner and use the accelerator to maintain a constant speed through the turn. • This will ensure that your motorhome is balanced and settled as you drive through the corner, improving comfort and tyre grip. • Taking this approach will also make it easier to stop or make last minute adjustments to your road position if something unexpected happens. 5. Reversing a Motorhome When reversing, proceed very slowly, especially if you are doing it blind (without a reversing camera or a second person to see you back). Although your wing mirrors will give you good visibility, always remember the blind spot behind the back of your vehicle. If in doubt, get out and look. Reversing cameras can be a great help and safety aid, especially if you drive on your own a lot.
