Larger Motorhome advice please

Chrisptm

My wife and I are planing to upgrade to a larger motorhome we are planing to buy a 2010 Autotrail 700se around 24ft 6ins long at the moment we own a Swift 590 Lifstyle just short of about 20ft 

Does the extra 4ft 6ins make a huge difference when driving reversing and parking up the Autotrail has a reversing camera so surely it's not that different ? 

I'm sure it's just a few doubts creeping in and all will be okay but it's an awfull lot of money to spend to find out that you just cannot live with a motorhome of the Autotrails length 

I would love to hear from anyone who uses a motorhome  of the larger type

Cheers Chris
