Can't overcome the fear of buying a Truck and TC.......

I agree that buying a new truck and camper is a big investment but have you thought about buying used and trying it until you see if you like it? Admittedly used prices have increased because of the pandemic, here in Canada certainly, but there are still bargains to be found. You could buy a new truck and used camper, used truck and new camper or both used used.
And don't let age scare you, I am 78 and have just sold my 5th wheel and have a new camper on order:)
