Welcome! Nice looking truck.
Hey, I thought 'going Toyota' was considered going to the
Dark Side? Ha, Ha.
Toyota in my Toyota-owning experience makes a great truck. I don't know your year Tundra well, but traditionally, what Toyota does well are small design details that make their vehicles last a long, long time (which most of the big-3 cut corners). That was especially true with the older Tacomas where they had things like dual wrap (military wrap) springs, oversized bearings, heavier axles, heavier u-joints and driveshafts, all the exhaust/cables/items tucked up nice and tight to the frame (not hanging down where they could get caught on branches or damaged off-road), multi-piston calipers (when everyone else was going 'cheap'), additional brackets to hold cables and exhaust so they don't rattle loose in the back woods ....and tons of other little details which go unknown to the average owner which, added together, yielded an overall more robust vehicle that generally outlast other rigs. I recall looking at the original Tundras how they had more cross members, stronger frame, larger brakes ....and a lot of other little details to make a 'better' (in Toyota's eyes) product. The drive train was practically indestructible! Consequently their vehicles cost a little more too. Those 'Extras' are probably items which will be noticed a lot more if the truck is used in extreme duty applications, or when it gets up to 250k miles when most of the competitor's trucks have worn out and are in the junk yard. But I haven't kept up on the new Tundras, and for people who trade often, those additional 'extras' don't really come into play.
On to Ram trucks, one good thing about Toyotas, is when they decided to make a 'real' full-sized truck they put the industry on notice and make each mfgr look at and 'improve' their product. So, some of the 'extras' Toyota used to be in a group of 1 with have sort of trickled down to the domestics. If you look at the 07 and up GMs, for example, there are a lot of improvements. Same with Rams and things like hydro-formed frame rails, rear plastic fender liners, dual piston calipers and so on. I'm coming from GM trucks. I looked all the domestics over well with a mechanic's eye and found a lot to like with Rams moreso than the others. I didn't get around to comparing them to Tundras but compared to Fords and GMs I think Dodge makes a superior product. Definitely the 5.7 is a 'strong' engine! The ride is excellent. I have high mileage on mine and it drove as well as GMs/Fords with 40k fewer miles. But that's just coming from my perspective.
As for what you should do, I guess you know your finances better. What do you do with your truck now? Do you need more seats, towing capacity, hauling capacity ..what are the main things you will do with it? Beyond that, keep looking and see if you find something you particularly like and what deal you can get ...go from there. When you go to trade off the Ram in 7 years it probably won't have the resale your Tundra has, but right now Rams do seem to be holding value pretty well. I'm surprised how man Ram's I see on the road now that I own one!
