Hi
I have just brought a new van and looking to kit it out and would like a split charge relay but looking for other people's experiences at charging up their leisure battery on a fairly compact round.
I do around 8000 miles a year using a pump 5 days. Anyone else found that they have been able to charge their leisure battery sufficiently with a split charge relay?
What
new van did you buy?
If its a brand new one with a 'smart' alternator and regenerative charging then this means that an ordinary SCR will not work on your van.
Grippatank have a good technical write up about why.

If its an older van, then I would say yes. It will pay for its once in its life. We had a leisure battery work fine the one day and then 'fail' whilst we were on a big job the following day. We were miles from home and with the engine left running we were able to finish the job. The wife was with us that day and she sat in the van whilst the engine was running.
I think of it as AA cover. You may never need it but you have it if you do.
I also have a volt and amp meter gauge 'across' my leisure battery. I can see what current is being drawn and what current the alternator is putting back into the battery when driving. That gives me a good indication if and when I must supplementary charge my leisure battery.
These days in winter I plug the charger in every night when I put the heater inside. In the summer I plug the charger in every second night or so, which means the battery is always fully charged.
