Seems they are not as happy with the experience as they used to be. Too hard to find nice places to stay, RV parks are too crowded. You have to make reservations 6 months in advance for the nice places in good locations. The ability to just pick up and go and/or stop anyplace and stay awhile is becoming increasingly difficult due to the demand for spaces.
Need to think outside the box to solve this one - and be prepared to venture a long way out of your comfort zone.. We have a fairly "different" solution although we are certainly not the first ones to do it.
If things get a bit stale in your home country and you are sick of 6 mile traffic jams to get into national parks so you can stay at a crowded campground with substandard facilities that you had to book no later than 9:01 am 364 days ago, then just store your motorhome and buy another motorhome in a different country. Say Germany. Then you can explore from Turkey to Morocco to Iceland to Russia to Ireland - which will take you at least 20 years if you figure on spending 4 months a year there. If so inclined you can learn a smattering of 20 languages and then have more fun trying to use the correct word in the correct country.
Then you will realise how easy and cheap it is and buy another motorhome in South America which will give you plenty to do for say 15 years at 4 months per year. And then with the new-found bravado derived from surviving all those terrible third world countries with their water that comes out of mountain springs rather than PET bottles, food that doesn't come triple packaged, Muslim ISIS and Kurdish PKK and Colombian FARK and Peru's shining Path around every mountain pass and jungle clearing and of course all the corrupt officials around every bend, you will realise that Canada isn't such a fearful place after all and that epiphany will be quickly followed by the realisation that Mexico is a wonderful place with wonderful people. So that adds another 20 years before you get bored and has a big advantage that it doesn't require buying yet another RV.
Then maybe Australia might beckon - buy a Toyota Troopy and rough it for a few months at the right time of the year and learn that drop bears really aren't repelled by smearing one's neck with Vegemite, that Vegemite isn't too bad dabbed sparingly on fresh bread thickly spread with butter, that our crocodiles are bigger than alligators as are our snakes, spiders, sharks, deadly jellyfish and fish and octopus. You can also see if you can find a place where you can drive for 4 days on your own and never have a cellphone service or GoodSam roadside service or a Walmart AND never see another human. Now that is scary. Do try to stay on the wrong side of the road though. It is safer. And watch out for animals on the road - kangaroos, Wombats, Donkeys, Goats, Buffalo, Horses and Camels. Hitting any is definitely a lose-lose outcome
AND since there is no real need to spend a lot of money keeping up appearances, all of your RVs will in total cost far less than one entry level diesel pusher.
And you will never get bored with the scenery, people or your lifestyle.
Or you can sit home on the back patio in your over 55's retirement resort waiting for the grim reaper to show up and put you out of your misery
No brainer, I reckon
