If it was me (and it was just recently) I would keep both. I have a 95 tacoma xcab 5 speed love the truck but with my dog it was/is no fun but I will keep it till I kill it. It doesn't cost me to much for registration or insurance and I can use it for everything a truck is good for like dump runs, hualing brush, getting into those tight spots that my new to me 94 cruiser can't go too, which honestly is'nt many. But for me the tacoma only gets around 18 mpg and the cruiser 13, so mpg differance isn't to much and the cruiser is by far more comfortable. Now if I had to choose between only having my cruiser and your truck I would keep your truck.
Yes, my truck does ride a bit harsh, even with the new and improved Alcan springs. I haven't spent enough time behind the wheel of an 80. Hmmmmmmmm.....
