I have a 5th wheel with a 50-amp shore power. I would like to install a 48v system using a EG4 6000XP Off-Grid Inverter. I was wondering if it would be possible to just route the wire from the shore power directly to the inverter and then from the inverter back to the fuse panel. In short, just inserting the inverter between the shote power and the fuse panel.

Yes, this would make the installation easier vs. adding a manual transfer switch also. You can choose between shore power pass through and inverter-battery power via the inverter control panel.
My concern would be with shore power that is not split for 240V operation. If you use the 30A adapter or a spot with older electrical you would only have single phase 120V. If the EG4 is set up for a single phase then it wouldn't be an issue.

Yes, that would be a legitimate concern. In that case it may be easier to get a separate battery charger that works with 120V and use it to just keep the batteries topped up while the inverter serves the loads.

I am doing a very similar setup. The plan is to put a chargverter input in case I have a 120V feed or need to power it off the generator. I plan on starting a build thread soon. I do like the idea of a separate input for the inverter. Might be cheaper than running a longer length of wire depending on where I put the 6000xp.
Just plan on a lot of room for the 6000xp. This is something I didn't think of initially. Curious where you would put it. Pictures would be great.

There are multiple threads on here discussing a 48v/12v converter. About 400w is the biggest I have found(victron}. I am considering leaving the magnum me2812 in place for 12v generated power to the sub panel. I intend to leave 2 206ah batteries in place for a bank of power for the sub. My sub carries the refrigerator, microwave, the lighting, and the wall plugs. The sub has a 30amp 120v two pole breaker. I am looking at the Victron 48/10000/140-100/100-120v inverter/charger. It produces 8000 watts at 25C. That is the same as my Onan generator. The Onan has a two pole 35amp breaker, but the tag clearly states that is produces 66 amps of 120v. The main panel doesn't have any two pole breakers except the mains. That means shore power is coming in 240 volt and being used as 120 volt. That is why I will be going with that particular Victron unit.
Not familiar with that inverter but like mentioned make sure it is compatible with split phase operation
I just did my camper a couple weeks ago and went with a victron setup. Their multiplus 2x120 (split phase) unit will pass through both 50a legs when you’re hooked up to a 50a shore power and will also combine both legs when supplying it with a single phase (15/30a) shore power which allows both legs of the rv side to remain powered up which in my understanding isn’t a function of just any old 120/240 inverter
The phases are joined in the adapter basically in any normal case, but if you were to plug into a 50a split phase plug that only had power on one leg, the victron still sends that power to both legs on the rv side
