Many on this forum are retired or getting ready to retire. I've always been single and planned for my retirement. So it came down to a MH pulling a toad or a truck towing a 5er. Its a lot easier to drive the little one up to the big one to hook up (in my case) or back the truck up to a 5er where you can see the connection point while backing up.
I know this is hard to consider, but think about the possibility of traveling as a single. If its a possibility, plan ahead. Also a good idea to be sure that everyone knows how everything in the RV works, even if you don't normally do that task.
