Welcome! :welcome4: Like you, we hired (twice) and after the second time decided "we have to have one"!
We have just done a 7600 mile trip round northern Europe, which many people, mostly non-motorhomers, think is an incredible mileage; actually average 91 miles a day, of which aout 500 were done in two day when we decided it was time to return. 5000 mls in two weeks is going some, but you did have a 'purpose'. We spent time in Poland and loved it - we'll be going back.
When you are doing your 'looking', remember to look at payload. You cannot assume that becasue a motorhome has 'x' number of berths that it will take all those people and their 'stuff'. Good liuck with your search :thumbs:
