Is it possible to rent a small RV (motorhome) in Vienna for a few weeks? I am a regular poster on the London forum and have had a friend ask me about RV rental. She is accompanying her parents to Vienna and then to a small town some 50K outside of Vienna in August. They are going to help with an excavation of a field where her uncle's plane crashed in 1944 during WWII. She has worked for over 20 years to retrieve the remains of her uncle who perished in the plane crash and bring them home to the states. During the excavation at this remote site, my friends' 80yr old parents will need to rest, use a restroom, etc. and she thought it would be easier for them if they had the use of a motorhome. It would be for August of this year. Any ideas for me? Thanks so much for your help.
