Motorhome Hire

[RosscoPCole]

I am looking to hire a motorhome next year for a weekend so I can take the family up from Dorset to watch the British stages of the Tour de France.
Has anyone had any experience of motorhome hire and what sort of outlay would be reasonable. Preferably I would like to hire something with its own bathroom so we do not have to rely on campsites.
Any recommendations and advice would be greatfully received.
Thanks in advance.

We rented a 4 berth motorhome last year for a trip to Spa and I think from memory the week was about £600ish
I noticed that there are sometimes some good deals on ebay
