E350 towing upgrades
 

I have an early ‘99 E350 7.3 conversion van. I believe it’s “early” because I’m told the fender badges indicate that for one, short of checking engine code. It was purchased to use for pulling our soon to be purchased travel trailer for full time travel. I have been contemplating some towing upgrades. Specifically upgrading the turbo to that from an e450 and then either adding helping springs or just changing out to e450 leafs all together. Curious to any thoughts and opinions. Thanks to all.
