Jud, I did put a Champion radiator like the one you have pictured in that yellow suburban I did. It worked, but I'm not sure how it would do with a big enclosed trailer or large 5th wheel. I know the owner towed a 16' enclosed from tennessee to Iowa 2 different times and said it did fine. But I can't imagine the weight was as great as a large enclosed filled would be.

I've used a lot of these and had good results. I've had very little luck getting radiators shipped to me so I prefer to walk in and buy one. If it's damaged, they walk back and get another.

Here's a really good one but it is pricey. I've put in a few of these and they are pretty nice. I can get you a price on one if you decide to go that route.

I put a 2nd gen intercooler on my brother's 84 K20 and it fit great. Had room to use the stock hood latch etc. Had plenty of room to put the grill on too.
