I have been all over the place. We started in a TC in the early 70s. Then went to a small 5th then a MH. We have been all the way up in MH to a DP 36', in 5ers all the way up to a 38' triple slide 20,000# GVWR rig. It was fancy with granite countertops and even had granite steps going into the bedroom with a built in separate washer and dryer. Then came back to TCs and then back up to a 5er and back to TCer again. We are here to stay till we can't travel anymore. Might have another TC or so but plan on staying with them. I don't want another MH so in order to tow my toys behind us I need a TC and truck.
But this is only something you and your wife can answer for your selves. Only both of you well know what you can live with.
